A Florida youth football coach was arrested after assaulting a referee. The article below explains that the youth program conducts background checks on all volunteers, apparently even on this coach who was found to have a criminal background after all.
Stories like this highlight that not all criminal background checks are alike. Many are very limited in scope and provide far less assurance than one might expect. Lets hope the referee fully recovers and be thankful that none of the kids were injured. In the interim, it appears that the league is shut down until an investigation can be completed.
