I saw a great scene in Blue Bloods the other day, and yes, I understand it's fiction and not real, but the answer was a good one:
Reporter asks why the cops shot an unarmed suspect.
Cop says, You see a suspect going for something that might be a gun, what do you do?
Reporter starts long winded answer....
Cop says, "Too late. You're dead."
Point being, if it is a gun, you have to shoot first if you're going to shoot at all.
Can't we just turn Congress off and then turn it back on again?
