As I posted in the past, I don't feel that long-term prison sentences are the answer (nor is the death penalty, what are you going to do, kill everyone?). The only time that I feel that they are, are when serious crimes are committed, or when it is deemed that the person keeps committing crimes, and cannot live in normal society.

Hence, when should life in prison (or the death penalty) be dolled out? Homicide cases of any kind. I don't care how old the person is, throw 'em in jail for life (or throw 'em on death row).

Treason should be deportation, and banning of reentry. Maybe, the reopening of Alcatraz (soon there will be a lot of people guilty of said crime).
