Not too sure...

It sounds a bit odd that he would only have the 'saw in the head' scene and none of the other missing footage from the Mandarin print of the movie.
However he does provide all of his details including a contact number and full address, so if he is a con-artist he would be pretty easy to track down.
I'm really not too sure about him. I'm sure Steve Kerridge said something about him being a con-artist so I wouldn't mind knowing how he found him out.
