This video is body cam footage of two Las Vegas Metro PD Officers encountering a man suspected as the offender in a domestic assault incident. The man hid himself in a closet holding a knife.
After refusing to comply with commands to drop the deadly weapon the suspect was tased, which didn't have the intended effect. The suspect continued to advance with a knife on the officers and was then met with deadly force.
Tasers are amazing tools but just remember they are not deadly force and are to be used against a knife (deadly weapon) only in conjunction with the deadly force response options at the ready whenever possible.
Stay safe guys. For another video I did on this topic check out:
