Does anybody know and is able to explain laws regarding murdering somebody who is a legal citizen of another country (say Mexico..) who is here (in the United States..) illegally?

I kind of want to join up or start another 'Minute Men' group.

It'd take me forever to explain my anger to people who haven't seen what it's like down here, so I won't.

I just need to know what the laws are and shit.
