“It’s not the size of the knife that makes a difference.”
—Speaking as part of an ongoing coroners’ inquest into the deaths of three mentally disturbed people (Michael Eligon, Sylvia Klibingaitis, and Reyal Jardine-Douglas) who were shot dead by police for wielding sharp objects in threatening ways, Bonner, who trains police officers in defensive tactics, made the case that knives are more dangerous than many people assume—the implication being that deadly force is sometimes a justifiable response. (The quote above was taken from the Star.) Sammy Yatim, who was shot and killed by police in July under similar circumstances, isn’t part of this inquest, but his case is being investigated by several different agencies, and James Forcillo, the officer involved, has been criminally charged.
