I tried to choose my words carefully -- the "suspicion" that Weaver had shortened a gun caused the raid. After people were killed, and after the siege was lifted, this suspicion was verified as a fact. My statement was that the incident occured because of the suspicion. I was correct when I said this.
Just for information an discussion ...
In Nov 89 Weaver sold two shotguns to undercover agents. I couldn’t find it but as I remember, Weaver admitted that he had shortened them but only to a legal lenght.
In Jun 90, frustrated that Weaver wouldn’t turn informant, charges were filed and warrants issued on Weaver for illegally shortening the barrels. Weaver claimed they shortened them after he sold them and he was being framed.
My earlier response was based on my memory but now unconfirmed ‘fact’ that Weaver admitted shortening the barrels. If Weaver did not admit that, then it is not a proven fact, only a ‘fact’ of the charges and warrants.
