Ontario Premier Dalton McGuinty is again rejecting calls for a public inquiry into police actions during the G20 summit in Toronto last June.

The Canadian Civil Liberties Association is calling for a full-scale public inquiry into what it calls the violent trampling of civil rights by police during the international summit.

However, McGuinty says there are already five reviews underway into the G20.

He says that's a lot of expertise and independent perspectives.

McGuinty acknowledged he has seen some of the videos that have emerged showing police violently arresting and detaining people, but he declined to offer an opinion on what he'd seen.

The premier also declined to say if it was appropriate for police to arrest people at Queen's Park, where he personally had invited them to protest during the G20 in a so-called free-speech zone.
