What do you mean by "have-nots" and "minorities". Most murders in America are committed by poor minorities against other poor minorities, with illegal weapons.Here's your problem. The have-nots in America don't arm to overthrow the government. They're manipulated to kill minorities and assuage their rage in that fashion.
The majority of non-murderers are legal gun owners, who are armed for many reasons. One is to ensure that the government can't treat them the way the Chinese government treats its citizens.
A shoot-out between whom? What fantasy world are you people living in?If there is a shoot-out, it's likely to lead to no improvement. Just an increase in the level of violence.
