I added a trigger icon to this thread. Tigerman, that behavior is way out of line. It is already an aggressive and illegal act, not to mention endangering the health of everyone in the building and others they come into contact with. I wouldn't advise confronting this man as a co-worker, but would report these actions to the appropriate supervisors. If you can prove that he is the one who did it, a police report would be appropriate.
