It says in the link you provided:
Boudreaux and his estranged wife had been going through mediation to resolve their custody dispute, which fell through, Whittle said..... Visitation papers had not been signed by a judge
It also says in the article that the mother let the paternal grandmother come and visit but when she tried to invite the father he "got ugly".
Let me know where my logic fails:
If old Nitzy wanted to come to YOUR house to take YOUR children home with me I should be able to because there is no court order preventing me. Further more you would be wrong for using force to stop me.
Is old Nitzy named on my children's birth certificates? If so, WE need to talk about support, Nitz.
If there was no agreement then that means that the father had just as much right to his children as the mother. They were HIS kids too.
