Without any more info. I would guess they kidnapped their own children after the government placed them in Grandmothers care. This won’t end well.
Were the CPS agents in charge left wing lezzies that hate whitey?
By itself, CPS can turn otherwise normal people into “anti-government” activists.
What crime did the parents commit? Did they try to start a business without the proper permits?
Did the parents make meth or sell drugs?
There is a reason that the grandparents asked for custody of these children.
