We gun owners would also fight it <i>very</i> hard, since we&#x27;d see it as a prelude to rolling this out for us.  Especially in the face of that, it would severely narrow the gun designs police would be able to carry, and since not everyone is alike, e.g. I hate the grip angle of the Glock, that wouldn&#x27;t be good.<p>Pure GPS + time reporting strikes me as useless, unless people think police are killing people &quot;off the books&quot; a lot more than I think they are.<p>Adding video isn&#x27;t likely to tell you much, since the predicates to drawing your gun are crucial and frequently wouldn&#x27;t be visible from the gun.<p>I also shudder from an engineering viewpoint at trying to get all this to work.  Service handgun are big enough as they are, and they add serious shocks, solvents, and primer and smokeless debris to the bundle of environmental stresses we demand of things like cameras on cops and their cars.
