What is the primary mechanism of action of a CEW?

• A. High-voltage, low-ampere electrical charge causing pain compliance or involuntary muscle contractions
• B. Lethal chemical injection
• C. Physical restraint without electrical output
• D. Sonic disruption

Answer: (A)

The main idea is that a CEW activates the body’s nerves and muscles with a short burst of high-voltage, low-current electrical energy, creating pain and involuntary muscle contractions that disrupt movement and gain compliance quickly. The high voltage helps the current penetrate clothing and skin, while keeping the current low reduces the risk of serious injury, so the result is temporary incapacitation rather than lasting harm. This neuromuscular disruption is what prevents the subject from resisting effectively, allowing for control and safety.

Lethal chemical injection isn’t how a CEW works—the device doesn’t introduce chemicals. Physical restraint without electrical output lacks the neuromuscular stimulation that causes the incapacitating effects. Sonic disruption relies on sound rather than electrical energy, so it would not produce the same neuromuscular response.
