In my dream, Canadian soldiers were everywhere, patrolling the streets. And they were going door to door in pairs, looting, everywhere. At each house, they knocked on the door politely. When we answered the door at our house, the Canadian soldiers bowed politely, and one of them said, "Hello, we're the Canadian Army, and we have come to loot. Have you anything to contribute?"

And that's Vancouver, which is mellow even by Canadian standards.

Alcohol and whipping up a tribal frenzy is a bad combination no matter what.

Midway through the first period, with Montreal already down 2–0,[38] Campbell arrived with three secretaries from his office (one of whom he would later marry).[39][40] The 15,000 spectators immediately started booing Campbell. Some fans began pelting him and his group with eggs, vegetables, and various debris for six straight minutes. At the end of the first period, Detroit had taken a 4–1 lead, and the barrage began again. Despite police and ushers' attempts to keep fans away from Campbell, one fan, pretending to be a friend of Campbell's, managed to elude security. As he approached, the fan extended his hand as if to shake Campbell's. When Campbell reached out to shake his hand, the fan slapped him. As Campbell reeled from the attack, the fan reached back and delivered a punch. Police dragged the attacker away while he attempted to kick the NHL president.[38] Shortly after the fan attack, a tear gas bomb was set off inside the Forum, not far from Campbell's seat.[39][41] Montreal Fire Chief Armand Pare mandated that the game be suspended for "the protection of the fans", and the Forum was evacuated.[38][42] Following the evacuation, Campbell took refuge in the Forum clinic, where he met with Canadiens general manager Frank Selke. The two wrote a note to Adams declaring the Red Wings the winner of the game due to the Forum's ordered closure.[39]

The departing crowd joined the demonstrators, and a riot ensued outside the Forum.[34] Rioters were heard chanting "À bas Campbell" (Down with Campbell) and "Vive Richard" while they smashed windows, attacked bystanders, ignited newsstands, and overturned cars.[36][38][43] More than fifty stores within a fifteen-block radius of the Forum were looted and vandalized.[36][44] Twelve police officers and twenty-five civilians were injured.[45] The riot continued well into the night, eventually ending at three A.M., and it left Montreal's Saint Catherine Street in shambles.[41][46] Police estimated between forty-one and 100 individuals were arrested.[47][48][49] Damage was estimated to be $100,000 ($910,638 in 2016 dollars[50]) to the neighborhood and the Forum itself.[42] One jewelry store alone estimated its losses at $7,000 ($63,745 in 2016 dollars[50]).[43]
