When all else fails, Smack em' in the Mouth!
It's not the exception! People who hang out with gang members, the vast majority of the time, are bad people. Jackson might not actually commit murder, but he's FAR more likely to get in some other sort of trouble if his known associates are these kinds of dumbasses.
It's not the only reason he got cut, but the Eagles are smart enough not to ignore that factor.
I don't think the gang affiliation had anything to do with why he got cut personally.
He had those same affiliations when the eagles gave him his big contract.
