Here's a story to make you feel sad.
My local (now closed) Long's Drugs had a policy (posted) stating that they look at all photos that are developed there. They did this to ensure nothing illegal was being printed at their stations as a liability. My step-sister worked there and once told me that it was also unwritten policy to throw out any photos containing non-standard nudity (meaning, like picture of newborns and stuff would be fine, but some person posing would not) and list on the package that the negatives were bad.
So, jump a head to her sixth month working there and my sister comes home looking like ten miles of bad road. Apparently, a kid brought in some film to be developed and all the pictures were of him in his underwear, the crap beaten out of him and holding a sign saying "PLEASE HELP ME". Turns out the kids father was abusing him, then keeping him home from school until the bruises went away. The kid knew our Long's looked at all images developed and came up with this plan of photographing the abuse, then getting the roll to the station.
They called the cops and we never found out how it all resolved itself.
