Please don't do that. There are better ways even if it might work. If you are the parent, then you have parental rights; and I'd say get the child's birth certificate and your own ID in order - a copy of the divorce agreement and go get your kid. You might want to have the state police accompany you - and maybe a journalist from the local paper or a TV crew. By all means take a voice recorder and have it going during all conversations with staff.
