I kind of agree, and disagree at the same time lol.
CPS/DSS/LE/whoever it is in any area- are pretty much forced to make a very swift decision when taking a child or children into emergency protective care if they are alerted to a situation or respond to a situation that has or may place children in danger.
But I don't think most cases are unwarranted- at least in the moment, kwim?
For example it's possible that when LE executed the warrant on SP's home-and if JP and the children were there- there was a domestic disturbance in process and LE deemed it a dangerous environment for the children.
There are a LOT of possibilities, unfortunately.
My very humble opinion, of course. I hope the children are safe now.
