What should we do with sex offenders

I think we should put the sex offenders away in jail for there life and don't have any kind of bail at all. Because if they get bail or get to get out of jail when there time is up they will just keep on doing it again and again. So children will not want to go outside anymore or do anything because they will be afraid of this sex offenders trying to get them. So to solve this problem, once they get caught they should be in jail forever!
