True, they should set up child abuse checkpoints too - think of the children after all.
People are willing to put a couple of weekends into making a middle school or high school competition happen. They're a lot less willing to do it if they have to go to an FBI station to get fingerprinted or produce a state and federal background check first. And I'm not talking about people with something to hide; I'm talking about people with a completely clean background who just don't want to be bothered.
Few years back got chased by a cop and ticketed (and scolded) for not restraining kiddo (small town and my clever 2yo somehow learned how to unbuckle themselves (even that houdini clip didn't help)). Warned I could get prosecuted for child neglect if I continue. I suspect the daycare has tipped him off.
