If I was Chris Brown's probation officer yesterday I would have tracked him down and given him a random drug test. On Sunday night after the Grammy Awards he was spotted smoking pot with Rihanna. Chris has already failed one drug test and this would have made it number two. It would have also made life way more difficult for him when he heads back to court. Instead, the probation officer probably did nothing and Chris will continue to believe he can do anything he wants to with no consequences.
