Which of the following is an example of a non-lethal weapon?

A Taser is considered a non-lethal weapon because it is designed to incapacitate a person temporarily using electrical pulses that disrupt voluntary muscle control. This allows law enforcement to subdue a suspect without causing permanent harm or death, which is the primary characteristic of non-lethal weapons. Tasers are often used in situations where officers need to control a subject without resorting to firearms or other lethal methods.

In contrast, a handgun, a rifle, and a knife are classified as lethal weapons. They can cause significant injury or death when used, as their primary function is to deliver lethal force. The distinction between lethal and non-lethal is crucial in law enforcement when considering appropriate responses to various situations while minimizing the risk of fatal outcomes.
