It’s long been acknowledged that CPS aka family and child protective services are only interested in going after the low hanging fruit. They have basically evolved into the tool of the vindictive, non-minority, middle class, suburban, “soccer mom” to antagonize non-custodial biodad on his visitations with his child(ren).
To go after REAL child abuse is both dangerous and politically incorrect. NO WAY would your average non-minority dad get custody in this case no matter how “poor” the biomom is. Full child support from biodad would be immediately retroactively court ordered and biomom would get full custody.
In this case, it seems biodad had a double ace up his sleeve (black? and gay) which was unfortunate for his innocent child. At that point CPS wouldn’t touch that politically correct case with a thousand foot pole as they would be accused of racism and homophobia.
In other words, a child is expendable.
