Yeah well there's naught you can do about someone being privileged. Also, why do you sympathize with them, if they have criminal records?
Two reasons. Most petty drug crimes shouldn't be crimes at all. Second, for similar offenses poor kids are much more likely to be incarcerated than the privileged. Had Mitt been poor and had the misfortune of having an officer of the law observed his haircut assault on another kid, he'd likely have been put in the back of a patrol car, arrested, and spent some time in jail even if he never did get convicted. Instead, even if a authority figure at the private school his CEO father put him in did observe it, probably the worst that would have happened to him would have been a literal slap on wrist (if the school used corporal punishment) and an injunction to go forth and sin no more.
Don't realy see where's there's much that can be done about the second, but I do have hopes we can get rid of the vast prison industry that exists because we mistakenly treat the mere voluntary consumption of something as a crime.
