Was just leaving my house in Airdrie on my way into Calgary this morning when two cop cars went past me hell bent. They headed south through Airdrie. I proceeded to head for the HWY and headed to Costco to fill up with gas. On the way I saw 5 cop cars and Suv's were set up around the field Just North of the Lowes. As I drove by the one cop had what looked to be a sniper rifle (I don't know guns that well) draped over his hood and was looking through a massive scope. The front of the gun had those legs like an A frame. I went and got my gas and proceeded to head to Calgary as I seen more cops surrounding the field. Anyone hear anything???
