The only advice I have to anyone is that if you god forbid ever do have to use any type of force (deadly or not) against anyone for any reason, absolutely DO NOT say a word to anyone (especially a cop) about it without a lawyer present. Without full understanding of the law, you could say something that could potentially fuck yourself even if you were in the right.
