When driving, traveling at 60mph, you have 10+ milliseconds to react, often that's not enough time. However, if you have a gun trained on me, with your freaking finger on the trigger, and it takes about 10ms to pull it, There is no way the typical meth head can whip out a holstered gun and shoot 2-3 people before you can squeeze that hair trigger. The fact that cops want put push that as the "fact of the matter" is sad, and pathetic. Go ahead and keep justifying your murder.
Truth be told, most cops are probably scared shitless because your bosses push this bullshit about millisecond accuracy and military precision in thought and action, and it's your bosses that really cause this death-toll, it's best you just quit repeating their crap and focus on reality.
