All CPS truly requires is the fear invoked by the agency's name (and reputation). To deny them at the door by asking they show a warrant is to pique their interest to an uncomfortable level and put you in a bad light. I was investigated years ago and was told by two different attorneys that I did not have the money nor power to fight them. Essentially, bend over and take it or risk the wrath of the CPS. I knew I had nothing to fear with the truth on my side and I fought without an attorney; the charges were dismissed in record time and my record was wiped clean. If they had taken one of my kids, though, you can bet your bippy I'd have put the second one into hiding!

Which, ironically, would be iron-clad cause for termination of your parental rights, because flight always has and always will demonstrate guilty intent.
