That's exactly what I would do to protect my kids from the foster care system.
I assume, then, that you also home school. I'm not trying to be a jerk here, I really do not understand why a group defending those who homeschool would be the first call you'd make if you were accused of child abuse.
Seems other lawyers might have greater expertise.
I wish that the Justice Department would be brought into the use of the CPS to harass homeschooling parents; what absolutely needs to happen is when this is over, the parents MUST file a lawsuit against the CPS. Everytime this happens to a homeschool parent, they need to sue them. Bring it into the public eye. See if it continues for very long after exposure.
The states that kept the government on the perimeter of homeschooling are the most fortunate, because they rarely go through anything like this situation. The people need to push the government further away from their homeschooling. We are the government, and we need to control the government.
