i understand that you might not think it enough of a punishment, but he has not gotten off scott-free - he did serve 40-some odd days in jail, pay god know's how much over the years in legal bills, and has had his freedom/security of movement restricted for the past 3 decades
a far cry from the cheese-grater/acid treatement for sure, but then i'd rather reserve that for the folks who've displayed a complete inability to control their sick needs - this guy does not appear to have repeated his offense so would appear to have learned his lesson via less draconian methods
operative word being "appear"...any other punk that skipped out on sentencing would be summarily thrown in jail...instead this fucker lives the high life for the next couple o' decades, building his career, being celebrated as a great artiste, blah blah blah...screw that...
