The King has done nothing to be asked for forgivance. If the same mob had been in DC , they would be crushed to death for vandalizing the public property. The King showed most restraint. Have you heard of "black panthers", the communist groups that existed in 50s and 60s in USA? They are nowhere now, they were crushed to death by the govt. itself. The King never did anything and then why does he need forgivance?
