Thanks for the info.
Your welcome.
I also just heard this Canadian reporter who was in the parliament building say that the shooting at the memorial was at 9:52 and he was in Center Block ( the parliament building) at 9:54 when he heard the gun shots. He said you had to be pretty fast the cover that much ground.
So, there are various reports on the number of gunman, and I am just paraphrasing what is on my DVR ( which is delayed one hour).
