What happens when the Bureau of Alcohol, Tobacco, and Firearms catches you trying to buy silencers and illegal machine guns in a Walgreens parking lot? You have to go to a lot of middle schools and tell kids that guns are dangerous. That's what happened to Atlanta rapper T.I. last year, when he got stung trying to build his own private arsenal. Now he's touring the country, doing community service by warning children about firearms and violence in the communitay. He showed up at West Oakland's Cole Middle School yesterday and, according to the Oakland Tribune, told the kids to "get an education, work hard, and stay out of trouble." Just like him! Wait, scratch that. Anyway, here's what makes this guy famous.
