OJ Simpson spent 1.5 years in jail without bail, waiting for a trial. He was found not guilty, and released. OJ Simpson stole back possessions stolen from him. Normally, that type of vigilantism would not be severely punished in Nevada, but everyone knew Simpson had gotten away with two murders, so he got a total sentence of 33 years. Because he was a good inmate, he was able to get the earliest parole after 9 years. Luckily for Simpson, no federal charges were involved.
I hate Michael Vick, but lets try to get through him without emotion. Vick is a truly great athlete, and he also ran a dog fighting ring which involved gambling. Torturing dogs should be extremely illegal, but is not. If they make torturing dogs illegal, it might make animal testing illegal, which we need for medical progress. So Vick got 2 years federal time, and 3 years suspended state(so zero time state) time for gambling. That is two years in prison, and both federal and state felony records. If he committed any other crimes, he would have to serve the 3 years state too.
Vick was able to make bail, because he was only charged with interstate gambling.
