IMO the issue is: Did the perp do something illegal... If they did... they need to pay the price for their choice. Punishment is a lesson to not make the same choice again... or not to make the choice the first time.
What I would like to see is: Folks doing the 'perp walk' for petty crimes (perp walk is when the news crews put your face on the evening news while the LE types lean you around in handcuffs). Wonder what those hot-shot check-walkers or non-tipplers would say to being paraded around in cuffs on TV??? Think they would like the public SHAME they would suffer in front of their 'bros'... <grin>
