Australian police to wear spy cameras during upcoming G20 summit

Australian police will use lightweight spy-type cameras to patrol Brisbane during the G20 world leaders' summit in November in an effort to be more transparent in controlling crowds, local media revealed on Friday.

Police do not want a repeat of G20 riots that occurred at the 2010 summit in Toronto, Canada, and are taking measures to ensure a safe event.

About 70 police will be issued with miniature cameras, which will be attached to their uniforms.

Australian Council for Civil Liberties president Terry O'Gorman told Fairfax Radio that this type of police technology is good for public security.

"It's good for police. It makes it difficult, if not impossible, for false complaints to be made against police. It's good for people arrested because it presents reliable evidence to the courts," he said.

"It saves a lot of time because pictures don't tell lies."
