Imagine how boring it must be to be a black teen. No job, shitty home life in the ghetto, living with 8 niglets and no father, can't fuck around on the internet because can't read, doesn't go to school because kicked out for violence or flunked out, no money for movies or booze, pissed off all the time because 80 IQ = life on hard mode. See other blacks have nice innocent fun at a child birthday party in the park, do what comes naturally and destroy something positive, cops show up and arrest your dumb ass. 

They literally have nothing better to do than roam around and wreck shit.
