CPS came to my house once to investigate my granddaughters ‘spiral break’ when she fell off her scooter and broke her leg. I let them in to talk to her but stated my conditions first. Not alone, I’d be sitting right beside her and if they strayed from the topic they would be stopped and escorted out the door.
They said okay and at first they abided but eventually they had to get to the part where they started asking about her Mom and Dad’s relationship. I stopped them, told her not to answer and escorted them to the door.
Never heard from them again. lol
You definitely need to know your rights anymore.
Only a fool takes legal advice from home intruders.
My response to any request to search/enter/whatever: "You do not have my permission, and I will be filing a lawsuit. Make sure you don't put yourself personally at risk along with the liability you are imposing on your agency."
