I have to take what he's saying with a big grain of salt.
I used to work in the office of a public school. I had to sign parents/care givers in and out, to pick up their children, and help keep track of parents who were DENIED permission to pick up their children.
I cannot believe how much he sounds like some of the outraged parents I had run into over the years, who swore up and down that the Family Courts were being totally unfair, and swore the other parent was lying and everything was a big conspiracy against them. I would feel sorry for them and look into the situation, but, in most of the cases, the outraged angry parent would not be telling me the total truth.
He sounds very much like some of the angry parents who tried to convince me to let them to take their kids home for lunch, or pick them up, even though they were on the 'DO NOT ALLOW' list.
Later I would discover they were denied access too their children for valid reasons. Driving drunk w/kids in the car, or getting busted with hard drugs w/kids present, or threatening to kill themselves and the kids when angry at the ex.....
I may be wrong, but I am feeling like AS is leaving out a big part of the story. Cops don't drag a teen out of their Father's home, without some kind of evidence that it is not a suitable place for him to be. The ex wife would need some kind of evidence to set that in motion. JMO
