A stun gun is a handheld device designed to deliver an electric shock to temporarily incapacitate a person. It works by emitting a high-voltage, low-amperage electrical charge that disrupts the body's muscle functions, causing pain and disorientation. Stun guns are often used for self-defense and by law enforcement to subdue aggressive individuals without causing permanent harm. These devices come in various shapes and sizes, often resembling a flashlight or a smartphone. While they are legal in many places, regulations can vary significantly, so it's important to check local laws regarding their use and possession.
