How can I get rid of a co-worker without losing my job?

I work for a Security Consulting Firm as a Guard. One of the other guards at the contract that I work is shooting porn in the building during his shift. I have some of the pictures that he took in the Executive Conference room and I want to use them to get him fired, but I can't figure out how to do it without getting myself fired or making us lose the whole contract........... Any Ideas?

Hire a hit man

Unless you were involved in the porn shooting too you wouldn't be so worried about losing your job would you?

If your company has a toll-free whistle blower hotline call and report him mention that you have proof of the act.

Mind your own business.......You just jealous 'cos he's earning a little cash and you not........

Any way to get a supervisor to stop by and do a spot check? Just say that you are uncomfortable with a situation that is going on there and can someone come take a look?

when you KNOW he is having one of his "photo shoots" -- invite the manager over to look at something that you thought was weird....
OR
Hide your own camera in the room where he does his thing....then send a CD to your boss on the Down low

YOU NEED TO TALK TO YOUR SUPERIORS IMMEDIATELY AS THE LONGER YOU WAIT AND KNOW ABOUT IT THE MORE LIKELY YOU TOO WILL BE FIRED.

You're going to have to do it anonymously. You could secretly mail the pics you have to the boss and set it up for him to catch the guy in the act. Make sure you are no where near the place when it happens. I wish you well with this.
