And I disagree with your disagreement. How do the store employees distinguish between "child pornography" and a parent taking pics of their kids having fun swimming, which just happens to be naked (as kids often are), or in the bath, or whatever? Not to mention, do you really think a child pornographer would be stupid enough to go and print something at a shop like that? How many people doing malicious things are really going to use a public service like that and risk getting caught? Do you think more criminals would be caught than innocents? Do you want the FBI knocking on your door one morning with a warrant after you drop off photos of your kids at the local printer? Sure it's an "innocent mistake" and you would eventually be cleared of any wrongdoing, but is it reasonable to go through that kind of ordeal just on the outside chance that it might possibly catch someone who could be doing something illegal? Surely there are better ways of finding and incriminating these people that will have less "collateral damage".

I totally agree with this view, and have a specific personal example that illustrates the result of the same sort of thinking. My mom was a 4th grade teacher for a long time until she retired - 30 years or so. During her last years there, her principal didn't like her- it seems that it was a problem of insecurity, as it seems that she (being young and female in a position that old men usually held) didn't get along with any teacher older than she, or any male teachers. But back to the subject, my mom saw physical evidence on a child on one occasion- the kid had a welt on the side of his face. He had never had any evidence of abuse before then- this was not a systematic thing, and she talked to him, and he said he'd smarted off to his mom, and she'd smacked him. This incident got back to the principal, and she called child services... and in addition, the police so that my mom got carted away from the classroom in cuffs in front of her kids. It turned out with investigation it was just that... he'd called his mom quite the bad word, and she'd smacked him across the mouth on the way to school. Child services found no fault in my mom's actions, nor the actions of the mom. It wasn't a regular occurrence at all. They tried to cover up their actions by saying it was better to err on the side of caution, but it's very telling that they tried to settle monetarily with my mom out of court for the whole police thing. My mom just got them to pay the attorney's fees and dropped it at that, even though the attorney had advised her that she could get a lot more, and indeed they were offering a lot more.
While it's true that we have civic responsibility, to prosecute someone because they don't police some other person's life seems very wrong.
