Last July, Faisal Hussain walked along Toronto's Danforth Avenue on a Sunday evening. He opened fire selectively, killing two people and injuring 13 more before turning the gun on himself. Not everyone encountered by Hussain that evening was shot, which is why his motivation is a crucial piece of the puzzle.
It took more than 24 hours for the Toronto Police to release the name of the gunman, and then there was the strange press release from Hussain's parents explaining that their son had been struggling with mental illness.
No radicalization to see here, folks, this is simply mental illness.
