Criminal Justice

With the "evidence" used to make precrime arrests, it can be assumed that the need for a trial is removed because there doesn't seem to be a question of innocence or any known reasonable doubt. However, the criminal justice system in this movie seems to leave out key concepts from our current systems such as sentencing or rehabilitation. Not only were people arrested for crimes they could/would have committed but it seemed as though they were declared guilty for the rest of their lives. This is a factor of injustice that I overlooked during my first viewing of the film but I believe this is an additional problematic trait of the precrime system amongst the obvious others.
