Gun

When the cops say "drop the gun", it's a good idea to drop the gun

I'm guessing you've heard about the 15 year old kid in Brownsville, Texas who was shot and killed by police for brandishing and refusing to put down when ordered, what turned out to be a pellet gun similar to the one pictured. 

Were the police justified? I say yes. After Columbine and Va. Tech, you don't bring any kind of weapon to a school. And, when cops tell you to do something, you'd better do it or you risk getting shot.
