And you are right. By the time they catch it something bad will have happened. But I would go to your Children Services Office and talk to them and express what is happening and that CPS and the police aren't doing anything and you fear for your children's safety. Show them your evidence and tell them what you said, just talk to your kids and they will confirm what happens at their dads.
