And for anyone reading, and just learning about CPS, the police showed up in the scene to protect the CPS officer. They have no authority to remove the child. They also can't affect the CPS officer.

Don't ever let them get their hands on your child. Until they have court ordered paperwork to abduct your child, they have not authority. And, at that point, they won't ask. They may even no-knock raid your house.

The CPS sees your child as a paycheck. They make bank for every child they snatch.
They almost never get the children who are actually being abused, like valued-customer said, they go after low hanging fruit. And those who are abusing, automatically lawyer up.

I am glad you kept the wolves at bay. I really don't believe the incentives every agency has to get your child. The doctor, the school, the CPS all have monetary incentives to get your child. (the doctor gets paid huge bonus if they VAXXX your child fully)

From a perspective of how bad things can go, you let the principal and CPS officer go very nicely and gently. In an informed world, where you are allowed to defend themselves, you would have burred them, and gotten kudos when you walked into town.
