The incident with his good friend was like 3 yrs ago. As far a the gang banging stuff, that could be someone hacking his twitter acct. I would have a hard time beleiving that from what I saw from his parents.
I saw this......Smith actually did apologize. I find it ironic that whenever Smith does something the public doesn't like, they always ask if he has "gang" ties.*P It could be that he just thought it was "cool". Why must he have gang connections I wonder.......... .......well not really, I know why. *P.S. Gangsters don't tweet*
