3 years I could do standing on my head. I spent most of my teenage years locked up and 3 years in jail just isnt worth running. I think I could get through 3 years of jail without having any major infractions that would keep me there longer, and the possibilities of gettng out and being able to get some sort of decent life together are still there.
10 years? Hell yeah I would run. I'd also die before I went back to jail, if possible. If not, as soon as I got to state pen, the first person to look at me funny would get something shoved in their eye socket. I'd end up dying in jail or getting the death penalty.
10 years without seeing my kid, 10 years without being in the workforce, a nice big mark on my criminal record to keep me from getting ANY gainful employment. 10 years of being locked up with the scum of the earth. If I did make it out, I'd be so screwed up and screwed over by the time I did, my life would be worth it's weight in sh!t anyway. Screw that.
However, I'm older and wiser now. I tend to avoid situations that could even raise the possibility of spending the night in jail. Life is a lot easier that way.
