hmmm let's recall some other police states and you can tell me how well it has worked for them....
So if I'm a cop and I see you loitering on street corner with your buddies I should pull out my sub machine gun and mow you down. I should then proceed to ascertain if you were up to no good? If you weren't oh well, the population is large enough it shouldn't matter. You got what you deserved for loitering.
If you're drunk and get in a bar fight the police should come shoot everyone involved and send you off to the morgue. You were obviously guilty of being drunk and accidentally/intentionally getting in fight. The gene pool is now better off.
If someone is robbing you and you fight back a cop should shoot both of you and then decided who was being robbed and send a nice halmark card.
Armed robbers are robbing a bank everyone in the bank should be killed because it's impossible to tell who the actual robbers are. Then we can figure out who is guilty. That's what you get for associating with robbers.
A car makes a wrong turn and ends up at a vital government facility. Everyone inside should be shot just in case who knows if they're a terrorist. They should have had GPS, there is no excuse to make a wrong turn in this day and age.
That's the America I want screw the Constitution and the Bill of Rights it's from an old outdated time. We could finally be safe from criminals.
