Possible, yes. But probable? Not all by its lonesome. That's the thing -- it is all so far fetched for bikers in the full context, that it's puzzling. It looks fake.

Yeah, that sentence jumped out at me too. Too bad we don’t know the ‘intentions’ of the Waco cops and their ‘confidential informant’.
