Open File has me reporting on the trial of Byron Sonne, a computer security consultant who was arrested three days before the G20 summit began in Toronto in June 2010. He says that he was documenting the summit’s $1-billion-plus security measures to evaluate how effective they were. After searching his home, police charged him with possession of explosive material; Sonne says the chemicals found in his home were for separate, un-related hobbies.

Here’s a backgrounder on the case.
