A lot of threads start with just a link. If anything that issue is the poster never even explains what the link discusses. That does constitute a form of drive-by.
In this case we have been discussing smart guns in other threads and I have made the suggestion that smart gun technology isn't focused on who can safely use it, but more on disabling it. An LEO wearing a transmitter would shut down your gun regardless of whether you needed to assist or not. The concept is to consider any other civilian gun bearer as a threat to law and order.
Given that there are over 330 million other guns in America, the more likely contention is that if the tech exists and it's the only legal firearm you can carry, the turnover in how many guns would be affected on the street is much higher. Since most of us don't carry long arms, those are already eliminated anyway, and the typical carry piece is usually a newer model handgun from the last ten years production. People buy guns as much for the leading edge technical improvements as for having the latest style, too, and with calibers getting a different scrutiny than in the past, we move into bores not considered previously. In the last 40 years we've transitioned nationally from .38 caliber revolvers to 9mm pistols, a major change, and the CCW carrier frequently carries .380 pistols.
Given typical sales a ten year change in carry could easily affect 25 to 50% of the guns carried by the public, if the State didn't mandate smart guns only for CCW. Should that happen, and it's speculative, some state like NJ could only allow a smart gun that would be disabled by the nearby transmitter. And those transmitters may be allowed to broadcast wherever a property owner sets one up, including retail, entertainment, government or whatever.
You and I would be forced to only have a nearly useless gun on us wherever we went about our daily business, where now we can at least expect it to go bang if we needed it. The anti gunners aren't playing for a quick win here, they never have. They play long term - grab an incremental step here, or there. M855 today, all military calibers tomorrow. A few smart guns today, all of the guns in the future. Because we keep buying New! instead of using the same old same old, we act in a way to help them further their ends. They use our consumerism against us.
You can't buy a new car without pollution controls, safety bumpers or even plain rims - TPMS is required. A modern house must have a larger electrical service with plugs every 6 feet whether you plan to use them or not. Code advances every few years, a new regulation is added, we need to do something about all those guns.
So, give cops a transmitter that turns them off. Cheap existing tech in the face of cell phones with GPS and Bluetooth.
Your gun charged up? Should be as it's the only way your red dot will work, and that has the chip to disable the interactive firing pin directly below it on the slide. I'm a 62 year old geezer and I can think that up. The Army wants that kind of tech to incorporate IFF on the battlefield at the soldier level.
Don't hide your head in the sand, or you won't understand what happened when you return to reality.
