I don't dispute the traps being illegal as our various government agencies have passed many laws designed at protecting the criminal and the victim can just suck wind.
The laws vary from state to state as to what type of force, how much force, what direction the piece of human debris was headed when the victim used force etc. etc.
Governments tend to be more trouble then they are worth. They tell us they only LEOs may use force but they know fully well that LEOs are a reactive solution at best and only in rare occasions can LEOs be pro-active in preventing crime. Then the same pieces of communist s#$% tell us we cannot protect ourselves.
Time has long passed when we should have used our 2nd Amendment rights to bring our government under control and now I believe it is too late. We have lost the protection of our constitution and the government is free to impose any unconstitutional law it can sneak past the less than supreme (political) court.
