Nah he will simply get a gentle slap on the hand and told to be a good boy by the judge.
As we have been discussing in here and have seen many, many times on TV, if your famous you are above ALL of the laws of this country and are able to do as you please when you please.
This was most likely a complete mistake. The arresting officer most likely didn't know who Bruno Mars was which is why he was even arrested in the first place.
It is sad but so true. Those living in the spotlight are able to get away with just about everything with out worry.I would love to see these judges finally grow some balls and start upholding the laws as they swore to do.
If you break the laws, then you should pay the price regardless as to who you are, who you know and where you live.
