[1]Why don't they take guns away from everybody because everybody is potentially the person [2]who murdered OJ's wife? Because there's no evidence to support that theory. If they get any kind of reasonable evidence (can be circumstantial), and take it to a judge, they could probably get a wiretap warrant or a search warrant. Then they can legally do what they're doing.
I don't want to ruin your post, so I'll just point out a few things.
First of all: I, too, feel it's completely wrong to look in and watch like the U.S. is doing.
[1] -- "The right to bear arms"; they would have to place annother amendment to nul that one. Also, take away our guns and we're a bunch on ignorant, insestual peices of capitalist shit. Also, violence is necessary, it prooves we're free. How many Dictators allow violence? The chance to take arms up in what you belive? I understand the idea that removing wepons will be good for getting rid of terrorists, but if some one is desperiate, anything's possible.
Also, if you where to remove wepons, that could just be one step closer to a totalitarian police state. There would be no way to fight back and prevent the facist regime from taking over.
[2] -- O.J.'s wife was stabbed, I belive. That's proof that if some one feels it's necessary enough, they can make due. You can't expect every one to give up everything that's potentially deadly, too.
