Mark Bolus was many things... but a victim was not one of them. Nor was he helpless.
He was also not an "animal" or a "predatore".
He was mentally ill, with a lot of impulse control problems, and the courts and police ACTUALLY WERE DOING WHAT THEY COULD TO HELP HIM (within the law and resources available).
In the end, he took his own life not because of "negligence" on the part of the jail but because he was a confused, frustrated, wound-up, young person.
Life just works out this way sometimes.
