the guns in the picture aren't real. every "news" outlet is showing pictures of the "arsenal" the teen possessed. only 1 was a real gun. the rest are either pellet guns or airsoft guns. he also had some knives, and some home made grenades. so, 1 gun (a legally owned 9mm rifle) & home made grenades, that's real deal. a table full of toys, not.

and when you say "armed," people generally think that they're actively carrying it. the kid wasn't strolling around with the toys, real gun, or grenades. they were in his bedroom.
again, i'm not downplaying the potential danger, but i'm just asking for a little truth in reporting by both the police and the news, and a little less exaggeration.
