It's because he's famous that he is held to higher standards than anyone else? He threw some eggs at a house and was accused of street racing while high/drunk by the cops (which all turned out to be completely not true). and now this pops up when he was just becoming "someone". What else has he done?
By your logic my Ex-GF should be locked up, hell even I should be thrown in jail pushing the death penalty.
She threw eggs at me at school, she's done many drugs, she's gone well over the speed limit, and she egged my (at the time) current girlfriends house. This all happened in high school when she was 17-18. The worst thing that happened to her was 1 suspension. Nobody else in the entire world knew about it or cared at all.
Point being, people do many many worse things than this brat but because he's under the spotlight 24/7 ANYTHING he does throws haters for a loop. DEPORT DEPORT OMG HE SAID THE "N" WORD. Get over it, he was a nobody at the time and he was 15. Nobody fucking died.
