How did anyone know what the intentions of the Denver three were?

From White House Gaggle

Scotty: Now, in terms of this issue, my understanding is a volunteer was concerned that these three individuals were coming to the event solely for the purpose of disrupting it. And if people are coming to the event to disrupt it, they are going to be asked to leave. There are always protest areas set up outside the events where people can express their views.

These three individuals acknowledged that they were coming to the event to disrupt it. They stated that publicly in some of the initial reports. And so my understanding is the volunteer was concerned about these individuals, and that's why he asked them to leave.

As far as I know, the three were ejected because of a bumper sticker. Even if your intentions were to disrupt the event, that still isn't proof that you actually would have. Unless of course one considers turning their back on the President as a disruption. (please correct me if I'm wrong)

The Carpetbagger Report has more info : The Denver Three’s attorney was not amused by the press secretary’s remarks...read on

More egregious, McClellan told White House reporters false information when addressing the staffer’s rationale for forcibly removing my clients…. McClellan’s statement is wrong, and the White House knows it. The Secret Service confirmed, after speaking with the mystery man in question, that the staffer removed my clients solely because of the bumper sticker on their car. This has been reported in the Washington Post and local Denver media, and has been confirmed to us directly.”

For what it’s worth, the same reporter followed up by asking if the White House has a role in directing these “volunteers.” McClellan said: “I don’t know if I’d view it that way.”

What an odd response. He never got around to saying how he does view it.
