Weird News: Tenn. Teen Shot in Behind Over Sagging Pants
The boys were walking through a southeast Memphis neighborhood when Kenneth E. Bonds yelled at them to pull up their pants, according to an arrest document. Police Sgt. Ron Perry said the teens refused and the three began arguing in the street. Bonds then brandished a semi-automatic pistol and threatened to shoot the teens.

I verify it's true. However, as you mentioned the man will face of aggravated assault for shooting the teen....who now is doing fine, but "His butts sore...& he wore bloody pants on the ground."..LOL!
I see so much of this everyday in Memphis and I believe it's cripples the way they walk too. I've been watching how they walk and it's not good for their body posture and legs. They may regret it as they age. I think it will affect them in a physical sense because of the walking hinderance after years of wearing their pants like that it's bound to affect their legs and posture...I feel sure of it.
