While I would never support any action where children are hurt, mistreated, or molested, some 'context' is lacking here. In recent years, it's the law to report cases of child neglect or abuse of any kind to the authorities. That wasn't always the case. The way such incidents used to be handled was to work through the chain of command. In other words, report to your superior and they would handle the problem with their superiors. It was basically out of your hands at that point.
For all any of us know, Coach Schiano and Coach Bradley may well have done what was considered 'the right thing to do' at that time. I certainly don't know and am not going to offer judgment based on that alone.
FWIW, I witnessed a superior physically assault a teenager during that time same time period. After reporting that incident to 'higher ups' no action of any kind was taken against my superior, who is well-known and widely respected. That was much more the 'norm' back then in spite of evidence very much supporting my claim. My superiors, when asked later, just said that I wasn't 'loyal' and was 'angry' at others. I found myself out of a job at the end of that year. By today's standards, you'd be asking for my job now, too, which would be highly unfair under any fair standard of justice.
It took quite a while for me to get past that event. People I had worked closely with and been very loyal to for many years turned their collective backs on me. I've moved on and continued working with teenagers. The last couple of years I've worked with teens who come from circumstances that are less than desirable. I'd not hesitate to go to the authorities today because that is required of me.
Times are different now and incidents involving the abuse or neglect of children are handled much differently. I just think we'd be wise to understand these incidents, while deplorable, took place in an era where 'justice' was handled in a much different manner.
