Why do the courts allow extensive visitation to a father indicated in an ACS report, and convicted of domestic violence

I have a stay away order of protection yet my children's father has extensive visitation. He was severaly verbally abusive, in front of my children, he has a conviction of domestic violence and an indicated report from ACS, do all the factors of abuse towards a mother matter at all? Is it only when a case goes to trial that the Judge finally know all the facts and then can modify the visitation schedule or possibly grant the mother sole custody? Domestic violence is a factor in custody, yet during the pendency of an action it does not seem to affect visitation for an abusive man. Please let me know your experience/thoughts on this, it does not make sense for the best interests of the children. thank you.
