I don't know, Chucky. If the van belonged to Rene Sanchez, wouldn't that be important? ;-)
Yes. If the van belonged to Rene, that would mean something, but it wouldn't mean that the agents were innocent of any of the charges against them, because HOW they were discovered is immaterial to the facts of what happened that day.
And of course there is absolutely no evidence whatsoever that Rene owns the van -- how do we know YOU don't own the van?
