Both the mayor of Vancouver and the Vancouver Police Department have called for photos and videos of suspects.
Mayor Gregor Robertson told a Toronto news station that pictures and videos submitted by witnesses would be used in making arrests, and the Vancouver Police Department announced on its Twitter account that it would post instructions for submitting photos and videos of suspects.
Several unofficial Facebook Pages have also been launched for the purpose.
"Lets post those pictures and put a label on the losers that made this city look so bad, ruined my neighborhood, and acted with out any class what so ever," one page says.
A Tumblr blog has posted what it calls a "riot criminal list."
One man earned particular negative attention -- so much so that is name is a trending Twitter topic in Canada -- for bragging about his crimes on Facebook.
