Corporal Punishment - Yay or nay?

Comparisons to how we discipline adults are hilarious. FTR, we ultimately discipline adults through the threat of pain and death. If you break the law, you will be arrested. If you resist arrest you will be physically subdued with pain and violence, or perhaps even killed. While you are incarcerated, you will be supervised by guards who have the authority to physically subdue you, or even kill you, should your level of misbehavior require it according to their rules and procedures.
If I could trick out my car to run on sanctimony, this thread would let me commute for a year for free.
