With the joint I work for, I don't post evidence. Someday, I'll tell you a story about a guy who borrowed a truck or two to do some personal work on a weekend. Unbeknownst to him, there was a crew scheduled to work that weekend. They came in and couldn't find their trucks. Not sure if they reported them stolen or not. That guy don't work here no more. Sometimes I have to tell people that even the trash belongs to the company.
Depends on local management/owner policy in those matters.
