Legal Question in Criminal Law in Georgia

Re: two for one sentencing rule

Some jails will give two for one credit for time served in that jail due to overcrowding. Usually with prisons they have a grid to show how much time a person will actually serve before being released on parole.

That being said, the determination of how much of a sentence someone will serve is completely up to the prisons and is not controlled by the courts. Also if the life in prison sentence is for a violent crime, they probably won't get out for a very long time. The shorter sentences are usually for nonviolent felonies, like drug offenses.
