(Andrea Huncar/CBC)About 200 people marched from Edmonton City Hall to the downtown police station on Saturday, adding their voices to the growing call for an inquiry into police conduct at last week's G20 summit in Toronto.

The protesters chanted, waved flags and listened to allegations of heavy-handed tactics used by police on protesters.

Police have been accused of using excessive force, unlawful mass arrests, lengthy detentions and other human-rights abuses at the event that brought the world's leaders to Canada.

Mark Senior said he attended the Edmonton rally because there are serious allegations he believes the major media aren't covering, including "letting crimes happen in order to justify a subsequent crackdown on people who weren't committing those crimes."

Keely Kidner, who spoke at the rally, described herself as "a concerned citizen" who went to Toronto because participants at the G8 summit, held north of the city without incident, and the G20 summit make decisions that affect everyone but those should be made by the UN.

Kidner said she left the grounds of the Ontario legislature, Queen's Park, about 30 minutes before police moved in on protesters there.

"And that's what really bothers me — that the designated protest area was violently shut down and that people were not given the chance to decide on what risk they were willing to take," she said.

Kidner said she has a long list of concerns that should be investigated through an inquiry, including the arrest of innocent bystanders, the strip-search and sexual harassment of some women and overcrowded cells where people held more than 24 hours with no access to lawyers.

"Today we are getting together and saying this is not right," Kidner said. "You can't squash free speech like this, and by exercising our right to free speech we're making sure that it's protected. And we're calling for a full public inquiry into what happened. We don't want this to happen again.

"Whatever people did in Toronto, they do not deserve to be treated that way. They do not deserve those torture-like conditions."

Kidner, who has been involved in other rallies in Edmonton and says she has always had a good rapport with city police, said her faith in police has been "shaken."

"I hope it doesn't happen again and we can re-establish trust," she said.
