UPDATE: Old man started jerking off so I tattled lol

I walked past him to look up a book and he switched tabs real quick (lol) so I waited a bit and snuck around and snapped a shitty picture of him with his "porn" open.

You can't see it in the pic but his hand was in his pants. It felt wrong not telling the librarians so I directed them to where he was (blatantly out in the open) and they went over to talk to him.

I assumed they were kicking him out but I guess he just got a warning because 2 minutes later he had his tabs back open with his hand in his pants again
