One major disadvantage of all types of corporal punishment is the use of it when the administrator is angered. That is when the line moves from punishment to abuse. Being so difficult to tell where that line is after the incident has occured, corporal punishment is rarely used.

Another disadvantage is its swift execution. Once administered, the individual is rid of their consequences for a behavior and feel freedom. This may indeed cause them to act inappropriately again because the pain is bearable.

Judicial corporal punishment doesn't fit with American society at all.  It's just not in our culture.  We view a government that can punish prisoners in this way as tyrannical, and put in the 8th amendment to protect us from such punishment.

As someone who is trained to be an educator, I am not trained to administer corporal punishment, nor would I want to be.  Since its purpose is fear, that also goes contrary to the educational process and distracts students from why they are there.  Plus, how would that function in today's lawsuit-happy society, where grabbing a student's arm can be cause for dismissal of the teacher?

Any number of parenting studies suggest that any control or conditioning achieved with kids through corporal punishment can also be achieved in other ways, and usually more effectively.

I do not really see any good to the idea of either judicial or school corporal punishment.

In the case of school punishment, I do not want someone else deciding when to hit my kid.  I trust my kids' teachers, for the most part, but not to the point of making that kind of a decision for me.

As far as parental corporal punishment goes, you can definitely argue that it is counterproductive.  You can say that a parent who hits their kid has lost control of their emotions.  You can say that they are only teaching their kid that violence is the solution to problems that you are unable to deal with in a better way.
