G20 protesters say they won't be intimidated by police

Groups planning to protest during this month's G20 summit in Toronto say they will not be intimidated by police tactics.

The Toronto Community Mobilization Network says police are spending hundreds of thousands of dollars on fences and equipment to control and bring pain to protesters.

Security personnel are erecting a link fence around several blocks of downtown Toronto surrounding the Metro Toronto Convention Centre, where the summit will take place.

Equipment that officers will have at their disposal include so-called sonic cannons, capable of emitting piercing sounds at painful levels.

The group claims police have been targeting community organizers, following them and visiting their workplaces, meetings and homes.

An area has been set aside at Queen's Park, where the Ontario legislature is located, for peaceful demonstrations.
