There are probably facts in there but anything not backed-up by proof would get tossed in court. From what I have read, little other than the fishing trip is documented and the money involved is not outrageous. I have no doubt that many of Silverstein's allegations are true...he's adopting the tactic that if you throw a ton of sh1t against the wall then some of it will stick.
Let's not shoot ourselves in the foot, though, Provest.
