Several of the peaceful mob participants had registered to attend the Harper event, but they were turned away by RCMP officers. Cara Dawson and Izzy Hirji were among those asked to leave the venue. A Conservative Party of Canada official approached them and indicated they were not welcome because of their involvement in an action that was perceived as a protest by party insiders. Dawson and Hirji tried to explain that it was not a protest and that they had registered to attend the campaign event, but the official could not be persuaded. RCMP Cpl. Tony Fowler of the “O” Division/VIP Security Section told the students the event was by invitation only and they would have to leave.
