In this video police in the UK safely disarmed a distraught man with a machete using safety shields rather than lethal bullets. Notice how they encircle and distract him, all the while maintaining contact and composure. This could have been the outcome when a Vancouver police officer engaged Tony Du near the intersection of Knight St. and 41st Ave. on November 22, 2014, if the Vancouver Police Department had a similar engagement policy in place. Instead an officer shot and killed Du "within minutes" of arriving on scene according to witnesses. Tony Du later died, and his family is devastated and traumatized by the loss.
