Especially when you're part of the non-favored ethnic group that perpetrates and celebrates the routine murder of innocent men, women, and children. Murder that is some times committed using construction equipment.

Now if you were a cop, and just received a photo of what looks like a member of the non-favored ethnic group with a murder weapon, saying "kill them" I'd bet you wouldn't just shrug it off. You take action to save innocent lives. Ask questions later.
