Vitt questions whether bounty evidence has been “falsified or tampered with”

One of my biggest problems with some of the NFL's supposed evidence is that they re-wrote or re-typed some of the documentation. I'm sorry but if you have proof why in God's name would you re-do any of it. Just show the original, condeming piece of evidence and be done with it. This just blows my mind.

The only reason I can think of is the NFL doesn't want the original hand written document out because then, someone can cross reference that to an unrelated document in order to figure out who the source is. What would happen to the NFL's, already tainted, credibility if it comes out that Mike Cerullo supplied the documents?
