Yeah, that is really horrible. Though I do know very good parents who bring their kids to marches and rallies - these days, though, all the cops have to do is say that they really like the nice law-abiding protesters but anarchists are ruining it for everybody, and then here comes the tear gas. That said, though, these people would probably recognize if things were going to get ugly from way off, and get their kids out of harms' way before it happened.
