Thx!

So if I try to escape from the prison in the US, without harming anybody and without damaging anything I still get additionally 3 to 10 years??

I was surprised to hear that such an attempt was ok in Europe in general, but this goes in my opinion in the exact opposite direction => I can definitely imagine anybody that tries to escape taking extreme measures to try not to get caught to avoid the repercussions.

You can easily look at up to 15 years. And there's a thing called MMS, mandatory minimum sentencing, which means REGARDLESS of evidence, the Judge's opinion or the facts, if you are convicted guilty of a charge, you MUST receive a minimum sentence and no less, which tend to be very strict. Drug charges, particularly dealing fall under this category.
