I dont think jones was ragging on chael for snitching on his friends buts rather exactly what he said "you call yourself a gangster but you snitched on your friends. Thats not gangster".
And about drunk driving... Yes he got in a wreck, but there aren't many people in this world that do drink and have NOT drank and drove.
The funniest part about that is that Jones seems to believe that Chael truly believes himself to be a gangster. Even though Chael has publicly made fun of that "gangster" lifestyle.
