<human>: I've had an OkCupid account for a couple months now. Met a guy who lives about an hour away who's a 40 year old PhD student (I'm 20). Anyhow, we had a successful date, and after an extended period of witty emails/texts/phone calls, we agreed that I'd spend the night at his place. He picked me up, we went back to his apartment and had dinner, etc.

At some point, he mentioned that he loved a UK tv show by the name of "The Mighty Boosh," but that he had a hard time finding streaming episodes online. I had my laptop with him, so he gave me his wifi password and I torrented the three seasons for him.

In the morning, he gave me his USB drive so I could copy the files from my laptop. I created a folder called "new folder" and copied the files into it. While they were in the process of copying, I accidentally bumped the laptop and unsafely ejected the USB drive. When I re-inserted it, I used my mac search utility to search for "new folder" on the USB drive.

A couple results showed up, and I clicked one. Suddenly, a stash of child porn. I'd say 13 pictures in total. Then, in a subfolder of that folder, another folder with more pictures that looked like child porn. None of these photos looked like they'd been taken by him, they looked like things he'd pulled off the internet. I looked at the image properties for one of the original 13 photos, it says the files were created in 1996.

I copied the entire flashdrive's contents to my computer because I was about to go back home, and I didn't want to bring it up and then get stranded in a strange city with no way of getting back and little/no cash.

Should I say something? Do something? Help, reddit.

Give me a shortened version of the text
<bot>: I stayed over at a guy's house, and while copying files to his USB drive accidentally opened a folder of child porn.
