@jmc88 - Like any law or lawful action taken in the United States, it must follow in line with the Constitution and the Eighth Amendment outlaws cruel and unusual punishment.
I say this because I have heard of some really weird sentences and probation requirements that have been administered by judges and have later been shot down by appeals courts because they did not fall in line with the Constitution.
I once hear of a man that was required to put a sign on their lawn saying what they were convicted of so their neighbors would know. I do not remember if this went to court or not, but I guarantee that this would not be allowed because of the Eighth Amendment and the unusual nature of it.
I am guessing there are limits outlined somewhere and I am really wondering where one could find exactly what the limits are as far as probation is concerned?
