Should Toronto Police disarm most officers? Our live chat was lively, as readers from both sides chimed in, including families affected by police shootings. Our poll was split down the middle, with 50 percent in favour of regular officers carrying guns, and 50 per cent in favour of cops being disarmed. Check out our Our live chat.

Our experts: Peter Rosenthal, a lawyer and Professor Emeritus of Mathematics and Adjunct Professor of Law at the University of Toronto, who has learned about police use of firearms primarily through his representation of a number of families of people who have been killed by Toronto police officers. He proposed this Big Idea.

Opposing Rosenthal is Steve Summerville, a former Toronto Police officer who is president of Stay Safe – Instructional Programs, a training and consultation firm, and a frequent expert witness in inquests. He completed his 24-year policing career as an Acting Staff Sergeant at the Ontario Police College where he served a secondment as a provincial trainer in the “use of force/defensive tactics” section.

We invite the experts every Tuesday at 1 p.m. EST to discuss a range of Big Ideas that are making our city buzz.

Speaking of experts, the Star will soon begin a series that will feature important ideas from Toronto’s Hidden Experts. Help us track them down by filling out our form.
