The two men appointed to review Vancouver's Stanley Cup riot say the police response isn't the only thing they'll be looking at as they investigate what happened.

John Furlong, former head of the Vancouver Olympic committee, and Doug Keefe, a former deputy justice minister from Nova Scotia, say work is now underway in their independent review of the June 15 riot, which caused millions of dollars of damage in the city's downtown.

They've been given an Aug. 31 deadline for a report that will examine whether the city and police were adequately prepared for the riot and make recommendations to prevent a repeat in the future.

Keefe says part of the investigation will invariably focus on the Vancouver police, which has faced questions over whether there were enough officers for the crowd of more than 100,000 people.

But Keefe says the police force is only a piece of the puzzle, and he and Furlong will look at a range of issues related to large event planning.

Keefe says it's impossible to guarantee there won't be another riot, but he says the goal is to manage such massive public events in the best way to prevent violence as much as possible.
