Another Investigative Lead for the Troofers

I've mentioned this video several times in the past, but I am struck by the fact that none of the "Truthers" has ever followed up on the revelation made by Patty Casazza:

Sibel brought us many whistleblowers and I submitted them personally to Governor Kean, who was the chairman of the Commission, and I said, "These people are not being subpoenaed. They will not come before the Commission voluntarily unless they are subpoenaed." And he promised me to my face that every whistleblower would be indeed heard. And most were not heard. Sibel was only heard because we dragged her in to surprise the Commission on one of the days we were meeting with them, that we had her with us. We met other whistleblowers on the side of the road of Maryland, you know, to hear what they could tell us. None of them revealed state secrets to us, by the way. But they had information, and basically, the government knew, you know, other than the exact moment, they knew the date and the method of which the attacks were supposed to come. And none of this made it to the mainstream media.

This is the sort of stuff the Troofers should be digging at. Who were these "other whistle-blowers"? Surely Mrs Casazza can give the movement at least a description of these individuals, which would help greatly in any investigation. I mean, we see these "ambush videos" by 9-11 Troofers harassing individuals in the media who have no special knowledge, when are we going to see someone press Mrs Casazza for details on her mystery informant, someone who apparently has solid evidence that the government knew everything but the exact moment of the attacks?
