From what I saw of the news conference, it appears the allegation that bikers were approached with an offer to be let go if they signed a liability waiver may very well be true.
Heard that as inconclusive. Jailhouse rumors.
I've speculated to myself that a slick lawyer (either side) may have made it up and floated it to simply test the water or pre-empt such a thing. Water over the bridge, at this point.
