I would pick it up if the camera works. I don't know why y'all our trippin if it's stolen. If you've got strict ethics, morals, or strong religious beliefs against stealing...just don't ask if it's stolen!! It's that simple.
Let me know where you are going to set your 7D down next. I know you won't mind if I help myself. Oh, and please set it down with the 24-105 attached. I've been eyeing that lens for some time now.
