The Phoenix Police Department has released a video about an officer-involved shooting that occurred on October 20 at 37th Avenue and Glendale Avenue. The incident began with a trespassing call involving a man who was impaired and armed with a large knife. When police arrived, a chase ensued inside a business, and efforts to detain the man escalated to violence, resulting in the use of tasers and ultimately a service firearm, according to the City of Phoenix.
