ST. CATHARINES, Ont. - Ontario Premier Dalton McGuinty is still refusing to apologize for passing a secret law governing police powers during last year's G20 summit in Toronto.

The vast majority of the more than 1,100 people arrested during the G20 weekend were released without charge or had the charges dropped, while 24 pleaded guilty and 56 are still before the courts.

But McGuinty says even though he personally invited protesters to Queen's Park, where many videos show police beating people and roughing them up, he won't say "sorry."

McGuinty admits his government should have done a better job communicating the law they passed for the G20, but says that's all he's responsible for.

The premier also rejects the idea of calling a public inquiry into the G20 weekend, saying if there is to be an inquiry it would be up to Prime Minister Stephen Harper to call it because it was the federal government's summit.

Civil liberty groups and citizens caught up in the police activities during the G20 have been demanding a public inquiry since shortly after the international summit last June.
