Its all politics fam. He touched on the drug thing by lowering the discrepancy between powder and crack cocaine (not lowered enough but its a start).
A lot of people are waiting for him to do something "racial", they even make things that aren't racial racial issues because that's what they want to hang him up on.
With that said even with this second term don't expect anything. Obama can't do shit about the local & state courts mistreating black folks.
Besides bro we got to start making changes ourselves, get out there and start boycotting these cases. Courts are open to the public, you can go and sit down and take notes in any case you want to or compile online news stories or something and spread the word.
Obama can't and won't do shit, you got to make the moves yourselves.
