Well, I think it's better for cops to have guns than not, since most thugs and criminals have them. ONly fair.
Now, I don't know where you got your sources about cops being power abusing and all... And people with disorders. While you're at it, you can badmouth the judges too, and maybe some leaders, who have waaaaay more power than a simple cop.
Actually, the more I think about it, the more I think cops should have guns ( in the US at least, since EVEYONE seems to have a gun).
you're generalizing,and I know that if YOU were a cop, you'd like to have a gun to protect yourself.
