It is unclear whether former Police Chief Shon Barnes' support of the surveillance cameras helped lead to Wilson asking him to resign last week. CAMERA CONTROVERYPolice believe the July 26 shooting at Seattle Center involved rival gangs but have only arrested one 15-year-old suspect. In the aftermath of the shooting, Wilson said cameras might be able to help police, but there were no cameras other than body models worn by police members. The latest controversy centers on Wilson’s July 7 directive to power down the Stadium District cameras right after Seattle’s World Cup fixtures concluded, citing the need to complete privacy and civil liberties evaluations. Last month, Seattle City Councilmember Bob Kettle also urged the mayor to keep cameras on following the end of the World Cup.
