Sonne possessed explosives to make a bomb: Prosecutor

Byron Sonne had an "obsession" with guns, explosives and the G20, and had amassed materials in his basement for the sole purpose of making a bomb, a Crown prosecutor says.

"The Crown doesn't have to prove what, when or where he (Sonne) was going to use the bomb,'' Elizabeth Nadeau told Justice Nancy Spies in her closing arguments Thursday.

Spies said though Sonne had explosive material in his possession, the Crown must establish he intended to combine them.

Nadeau admitted police didn't find drawings or plans for a bomb plot. But she said Sonne couldn't have had any other motive in mind for storing the trove of chemicals and devices police found in his basement.

Nadeau said if Sonne simply obtained the material in a bid to draw suspicion from authorities and deliberately raise "red flags,'' his actions don't support that claim.

"(That) makes no sense,'' Nadeau said, arguing Sonne took potassium permanganate out of its package, left no warning tags nearby saying it was hazardous, and kept it in his laboratory where he had processes on the go.

Court has heard suggestions that Sonne, 39, a hobby chemist and computer hacker arrested before the G20 Summit in 2010, was trying to test the limits of G20 security and intelligence, and trying to expose vulnerabilities in advance of the gathering of world leaders in Toronto.

Sonne took pictures of security cameras set up before the summit and also photographed the downtown security fence.

He faces four counts of possessing explosive devices and a count of inciting others to commit an indictable offence. Sonne's defence lawyers are to begin their closing statements Friday.
