Florida authorities said the state's 'red flag' gun law has been used more than 3,500 times since it was passed, just three weeks after 2018's deadly Parkland shooting.State legislators from both sides of the aisle passed the red flag law just three weeks after authorities said a mentally-disturbed man, Nikolas Cruz, fatally shot 17 students and staff at Marjory Stoneman Douglas High School in Parkland, Florida.February 14 is the shooting's second anniversary.Investigators did not act on reports that shooting suspect Cruz was threatening to carry out a school massacre. But even if they had, it is likely he would have been allowed to keep his guns because he had no felony convictions or involuntary, long-term mental commitments, they say. SharePinellas County Sheriff Bob Gualtieri, who leads a commission that investigated the massacre's causes, says the shooter would have easily qualified for a red flag order.Gualtieri says while it is impossible to say that would have prevented the shooting, the gunman wouldn't have been able to legally buy weapons or ammunition, making his preparation difficult.' Students formed a chain as they moved away from the shooting scene on February 14, 2018Within two weeks, a hearing is held during which the judge decides whether to take the person's weapons away for a year. Police agencies can apply for an extension if there is evidence a person remains a threat after a year. The news that Florida authorities have used the red flag gun law 3,500 times since it was passed comes on the second anniversary of the Parkland shooting.
Q: Can my ex-husband buy an air rifle for our nine-year-old? My son seems a bit young for one? Singstar pop songs. A: It is against the law for anyone under the age of 18 to buy or own an airgun or airgun ammunition, even if it is given as a gift.An adult aged 18 or over can, however, buy and own a legal-limit (sub12ft/lb) airgun and allow a child as young as your son to shoot under very close. Demonstrators in San Francisco marched at a student-led protest against gun violence held one month after the deadly 2018 shooting at a high school in Parkland. Retro Report, led by Kyra.
A scene from the vigil the day after the shooting is shown hereThe AP analysis shows that from March 2018, when the law was enacted, through December 2019, there was a wide disparity in its per capita usage in Florida's 67 counties.Twenty issued at least one for every 5,500 residents during that time period, the statewide average. Three issued at least one for every 2,000 residents, including Gualtieri's Pinellas County, which includes the Tampa Bay area, and has nearly 1 million people. Highlands County, near Lake Okeechobee, ranked No. 1, issuing one for every 850 residents.On the other extreme, 12 counties issued one for every 30,000 residents or less. Two neighboring Panhandle counties - Escambia and Santa Rosa - issued one for every 100,000 residents or more. Another nine small, rural counties issued none.Highlands County Sheriff Paul Blackman said he doesn't know why his county is No. 1, but he noted that his deputies average two calls daily for mental health crises.
The county has just over 100,000 residents and was the scene of a bank shooting last year that left five women dead.'
The Light GunA light gun is a for and a for and, typically shaped to resemble a. In and, it can also be a.Modern screen-based light guns work by building an optical sensor into the gun, which receives its input from the light emitted by on-screen target(s). The first device of this type, the, was used on the computer.The light gun and its ancestor the light pen are now rarely used as pointing devices due largely to the popularity of the and changes in display technology—conventional light guns work only with monitors. Main article:The first light guns appeared in the 1930s, following the development of light-sensing. It was not long before the technology began appearing in shooting games, beginning with the in 1936. These early light gun games, like modern, used small targets (usually moving) onto which a light-sensing tube was mounted; the player used a gun (usually a ) that emitted a beam of light when the was pulled. If the beam struck the target, a 'hit' was scored.These games evolved throughout subsequent decades, culminating in 's, the company's first successful game released in 1966, which required the player to target cardboard ships.
Periscope was an early, and the first arcade game to cost a per play. Sega's 1969 game Missile featured electronic sound and a moving film strip to represent the targets on a projection screen, and their 1972 game Killer Shark featured a mounted light gun that shot at targets whose movement and reactions were displayed using onto a screen. Released the Beam Gun in 1970 and the in 1973, followed in 1974 by the arcade game, which used to display the target on the screen. In 1975, Sega released the early light gun shooters Balloon Gun and Bullet Mark. Use in video games The video game light gun is typically modeled on a weapon (usually a ) and is used for targeting objects on a video screen. With, the light gun can also simulate the of the weapon. The first gun for a home console was in fact a big rifle, the 's, which looked very lifelike and even needed to be 'cocked' after each shot.Light guns are very popular in arcade games, but had not caught on as well in the home market until after the (NES), (SMS), (SNES) systems and Atari XEGS.
Many home 'Pong' systems of the 1970s included a pistol or gun for shooting simple targets on screen. 's for the NES is the most popular example of the light gun, and its most popular game.Traditional light guns cannot be used on and, and have problems with.There are also light guns for, and several other console and arcade systems.
Recent light gun video games include, and.In, released the for the, a peripheral which is actually a plastic shell that houses both the and for gun-style video games. While it does not contain any traditional light gun technology, the peripheral makes use of the Wii Remote's built-in to shoot targets that correspond on-screen. Its name is a reference to the classic for the. Sony has also released attachments that house the motion controller in the form of a pistol and rifle, the latter named the Sharp Shooter.'
S 3 also uses an infrared optical sensor system similar to the.Design The 'light gun' is named because it uses light as its method of detecting where on screen the user is targeting. The name leads one to believe that the gun itself emits a beam of light, but in fact most light guns actually receive light through a in the.There are two versions of this technique that are commonly used, but the concept is the same: when the trigger of the gun is pulled, the screen is blanked out to black, and the begins reception. All or part of the screen is painted white in a way that allows the computer to judge where the gun is pointing, based on when the diode detects light. The user of the light gun notices little or nothing, because the period in which the screen is blank is usually only a fraction of a second ( see ).Sequential targets The first detection method, used by the Zapper, involves drawing each target sequentially in white light after the screen blacks out. The computer knows that if the diode detects light as it is drawing a square (or after the screen refreshes), then that is the target at which the gun is pointed. Essentially, the diode tells the computer whether or not the player hit something, and for n objects, the sequence of the drawing of the targets tell the computer which target the player hit after 1 + ceil(log 2( n)) refreshes (one refresh to determine if any target at all was hit and ceil(log 2( n)) to do a for the object that was hit).A side effect of this is that on poorly designed games, often a player can point the gun at a light bulb or other bright light source, pull the trigger, and cause the system to falsely detect a hit on the first target every time.
Better games account for this either by detecting if all targets appear to match or by displaying a black screen and verifying that no targets match. Cathode ray timing. The blue and pink made for the Sega Genesis.The second method, used by the 's and computer, is more elaborate and more accurate.The trick to this method lies in the nature of the inside the video monitor (CRTs were the only affordable TV monitors in the late 1980s and early 1990s, when this method was popularized). The screen is drawn by a scanning beam that travels across the screen starting at the top until it hits the end, and then moves down to update the next line. This is done repeatedly until the entire screen is drawn, and appears instantaneous to the human eye as it is done very quickly.When the player pulls the trigger, the computer (often assisted by the display circuitry) times how long it takes the electron beam to excite the at the location at which the gun is pointed.
The light gun sends a signal after sensing the sudden small change in brightness of a point on the screen when the electron gun refreshes that spot. The computer then calculates the targeted position based on the monitor's horizontal refresh rate (the fixed amount of time it takes the beam to get from the left to right side of the screen). Either the computer provides a time base for the horizontal refresh rate through the controller's connector (as in the Super Scope), or the gun reads the composite video signal through a T-connector on the A/V cable (as in the ). Once the computer knows where the gun is pointed, it can tell through collision detection if it coincides with the target or not.Many guns of this type (including the Super Scope) ignore red light, as red phosphors have a much slower rate of decay than green or blue phosphors.
As a result, some (but not all) games brighten the entire screen's green/blue pixels somewhat when the trigger is pulled in order to get a more reliable fix on the position.Display timing is not possible with plasma, LCD, and DLP monitors, since they do not have an 'off' state between refreshes. Their digital signal processing electronics also may introduce a nontrivial lag between the signal input and display output, which is not predictable because it varies between monitor models and brands and even between mode settings of a single monitor. A lag which is not very significant for player feedback may be enough to completely destroy the accuracy of a display-timing based light gun system.Infrared emitters A new method was developed to compensate for display technologies other than CRT. It relies on one or several light emitters placed near the screen, and one IR sensor on the muzzle of the gun. When the trigger is pressed, the gun sends the intensity of the IR beam it detects.
Since this intensity depends upon both distance and relative angle to the screen, angle sensors are located in the gun. This way a is solved, and the muzzle's 3D position relative to the screen is calculated. Then, by projecting the muzzle on the screen with the measured angles the impact point is determined. An early example of this technology (though not using IR) can be seen in the, which used three ultrasonic sensors serving the same function as the IR emitters used in some lightguns.A simpler variant is commonly used in arcades, where there are no angle detectors but 4 IR sensors. However, this can prove inaccurate when shooting from certain distances and angles, since the calculation of angles and 3D position has a larger margin of error.Other variants include 3 or more emitters with different infrared wavelengths and the same number of sensors.
With this method and proper calibration three or more relative angles are obtained, thus not needing angle detectors to position the gun.Sometimes, the sensors are placed around the screen and the emitter on the gun, but calculations are similar.The uses an infrared video camera in the handheld controller, rather than a simple sensor.This family of methods are used for the, and modern light gun games.The downside of this method is that it's not as accurate as a traditional light gun. The additional IR image processing results in lag or 'cursor drift', i.e. When quickly sweeping the light gun across the screen the crosshair will seem to drag slightly behind where the light gun is actually pointing.Image capture When the user pulls the trigger the screen is replaced for a split-second with a seemingly random display of black and white pixels, or groups of (blocks). The light gun contains a fine-resolution but low pixel count digital camera with a very narrow field of view. With just a handful of the dot image pixels captured, the gun converts the small image into a which allows the computer to locate the exact position the gun was pointed at.
This method is compatible with any screen of any size. The size of the screen and distance to shooter is entered into the gun driver software to determine the dimensions of the random blocks/pixels to best allow rendering on the light gun CCD.Rectangular positioning Similar to image capture, except rectangular positioning disregards any on-screen details and only determines the rectangular outline of the game screen. By determining the size and distortion of the rectangle outline of the screen, it is possible to calculate where exactly the light gun is pointing. This method was first introduced by the Sinden Lightgun.

The light from the LCD TV or screen is used as reference point. Optionally, a thin rectangular border can be added to the display content, for games with a dark graphics theme.An advantage of this method is that the size and distortion of the rectangle screen outline can also be used to determine the position and angle of the gun relative to the screen.
Theoretically this can be used to create a 3D tunnel effect, by moving the gun around the screen to hide behind scenery or peek around corners.Multiplayer A game that uses more than one gun reads both triggers continuously and then, when one player pulls a gun's trigger, the game reads that gun until it knows which object was hit.Positional guns Positional guns are fairly common in. A positional gun is a gun mounted to the on a swivel that allows the player to aim the gun. These are often confused with light guns but work quite differently. These guns may not be removed from the cabinet like their optical counterparts, which are tethered and stored in a mounted holster. They are typically more expensive initially but easier to maintain and repair. Games that use positional guns include, the arcade version of,.
Sometimes use light guns.A positional gun is essentially an that records the position of the gun to determine where the player is aiming on the screen. The gun must be calibrated, which usually happens after powering up. Early examples of a positional gun include 's in 1972, 's in 1976 and in 1977, and 's in 1978. Some games, however, have mounted optical guns, such as Exidy's.Light gun models. Ashcraft, Brian, (2008) Arcade Mania! The Turbo Charged World of Japan's Game Centers, p.

Morgan McGuire & Odest Chadwicke Jenkins (2009), p. 408, retrieved 2011-04-03, Light guns, such as the NES Zapper or those used in the House of the Dead series, are distinctly different from positional guns used by arcade games such as SEGA's Gunblade NY. Light guns differ from positional guns, such as in Gunblade NY (bottom), that are essentially analog joysticks.
Positional guns are essentially analog sticks mounted in a fixed location with respect to the screen. Light guns, in contrast, have no fixed a priori relationship with a display.
Yo-Sung Ho & Hyoung Joong Kim (November 13–16, 2005), p. 688, retrieved 2011-04-03, The two routes to conventional gun control are light guns and positional guns. Light guns are the most common for video game systems of any type. They work optically with screen and do not keep track of location on the screen until the gun is fired. When the gun is fired, the screen blanks for a moment, and the optics in the gun register where on the screen the gun is aimed. That information is sent to the computer, which registers the shot.
Positional guns are mounted stationary on the arcade cabinet with the ability to aim left/right and up/down. They function much like joysticks, which maintain a known location on screen at all times and register the current location when fired. at the. at the. at the.
