If you're blaming weed you are dumber than Erick. You think this kid is telling any truth when talking to police and facing life in jail? His own grandmother said it was for fun. Worse case scenerio David smoked some weed, like every average kid his age. Doesn't mean he, or your own kids deserve this. This is the result of mentally ill teens not substance abuse. Gangs kill over weed because it's currency and comes down to them feeling disrespected or some other butt hurt. The issue is gangs. If weed was causing this there would be hundreds or thousands of murders every year. Over half the state probably has smoked weed to no I'll effect. Notice how the punks story was careful to mention that he only ever watched? If you feel like pointing a finger, point it at the adult who let this depraved punk have easy access to guns. Who ever they belong to should be charged with negligence resulting in a death. Music didn't cause this, weed didn't, video games didnt. It was pure mental depravity.
