The incident began with a complaint about a suspicious vehicle. Insp. Al Ramey said "A member with six months' experience attended the scene and was confronted by a man brandishing a knife. The man attacked our police officer, cutting him severely in the forearm. Our member responded with the deployment of a conducted energy weapon [assume taser], managed to immobilize the suspect and take him into custody."It is good to read about a story that describes an incident where it appears that a potentially-deadly weapon was used successfully and (assuming the story is accurate) without any moral/ethical downsides. As some comments on the CBC website have noted, the officer could have drawn his revolver and plugged the suspect in the chest.
That he chose to reach for his taser is a questionable decision (due to the relatively high rate of ineffective deployments). But perhaps the details not mentioned made his choice rational.
Critically - please compare the rate that such apparent success stories appear to the rate of taser use.
UPDATE: More details here [LINK]. Subject is 61 years old.
Speculation Alert - I wonder if the story will eventually shift so that it is revealed that the stabbing occurred because the officer was relying upon his untrustworthy taser?
