Where's the Justice.....?

an ex friend of mine i don't speak to him because of what he done he got sent to prison for manslaughter which is a lot less than murder in the UK apparently how ever u kill them pathetic sentences which he is now out of prison. he gets student of the year at his college he goes too now still goes out and party's what has he really been punished for nothing i could go out and do the same thing he done.
