We have sentencing guidelines. Some are sentenced to prison, some get parole, some are sent to mental facilities, some a combination of two or more of those. When the time is up and the powers that be decide a person has completed their punishment and/or treatment. They are let out. It's that simple. Hinkley has served the time he was given.
Unless a person gets life without the possibility of parole or gets a death sentence...there's an end date for incarceration.
