I do think they should be legal and unregistered, when there is a rash of autistic kids or people with extremely pronounced mental illness killing people let me know. Because most of these shootings couldn't have been stopped by another law, and most of these killers seemed strange but normal enough until they did the deed. How do you explain normal people who do killings? are we all mentally ill? just sometimes? see where this goes.. missed the mark again bro. You ever going to add anything? or we just trolling again?
