Why is it that convicted criminals don't serve their entire prison sentence?

I hate to nitpick, but only convicted criminals serve sentences. "Someone who get sent to prison for 25 years shouldn't get out in 5." It's best to think of a sentence as being something other than a period of time spent incarcerated.

It's more like a commitment - even after you get out in 5 (that seems an exageration if you know of a specific case, please cite it) you are still under parole supervision. Judge's know that someone who gets a sentence will not necessarily serve the entire period - they account for that when they impose sentence. So when a defendant gets a sentence of x that turns out to be Y, you know it was Y that the court was shooting for, and anything above that is the defendant's own fault.

Also, it makes it harder for the defendant to successfully appeal based on an excessive sentence charge. "Why does our legal system work this way?" You can pick a number of reasons, but mostly they deal with the direct and collateral costs of incarceration.

Running prisons is ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
