Movie about a man who goes to prison for shooting one of his family's murderers

I saw this American movie on TV 1 or 2 years ago. I got halfway through then the recording stopped. A brief description follows:

A family orders Pizza for home delivery. The doorbell rings. The wife thinks it's the pizza delivery. She opens the door. Thugs burst in, rape and murder the wife and daughter. The husband arrives home and finds his family murdered. The thugs are arrested. There is a court case but they get off on a technicality. The thug steps outside of court and walks down the steps. The husband, waiting outside, snatches a gun from a policeman and shoots the thug dead. The husband is then arrested, put on trial and sent to prison for murder. In prison he befriends others who devise a breakout. A group of prisoners escape on a work bus, kill the driver and eventually escape by train.

That's as far as I can remember. Please help with the title or name of actors in movie.
