If, when confronted by the authorities, you act/talk like a like you can expect to be treated like a thug.

Do NOT keep it real. Kiss their asses three bags full. No shame in that. In your case it may have saved you $1500 and the hassle of probation and the humility of community service.

Your going to jail will not help your brother anymore than some smart ass cop whose only reason for being a cop is to harass people like you.

Just another case of keeping it real gone wrong.

Hope your brother is doing better and everything works out for you.
