In the case of these people who have been arrested over 100 times, this must not involve very serious charges, since they have been released so many times. I doubt a judge would release someone convicted of murder before 20 years, or even individuals convicted for bank robberies, armed robbery, and so on.
Do you really know of cases where people have arrested over 100 times? Are these not, as I have seen at times, unfortunate souls, people of very limited intelligence who commit petty crimes, like shoplifting and petty larceny, simply so they have a roof over their heads in the winter? Do you really know of cases of dangerous criminals who escape justice 99 or 100 times?
