tazer

Tazer, often spelled tazer, is a term used to refer to electroshock weapons, most commonly the TASER devices developed and marketed by Axon Enterprise. The name TASER originated as an acronym for Thomas A. Swift’s Electric Rifle, and while TASER is a brand, “tazer” has become a common nonofficial spelling for these devices. In general usage, tazer can also describe other stun devices that deliver a high-voltage, low-current electrical discharge intended to temporarily incapacitate a person.

Operation typically involves projecting two small darts connected by insulated wires into the target. The darts are designed to pierce clothing and skin and transmit a pulsed electrical signal that disrupts the body's neuromuscular system, causing involuntary muscle contractions and temporary incapacitation. Some models also offer a contact mode where electrodes are placed directly against the body. The goal is to allow restraint or increase distance to avoid physical confrontation without lethal force.

Variants include handheld, dart-based devices used by law enforcement and security personnel, as well as civilian stun devices that operate without projectiles. Popular police models have evolved to include features such as improved accuracy, multiple shot capacity, and data logging for accountability.

Safety and legal issues surrounding tazers are debated. Risks include cardiac events, seizures, burns, and injuries from falls or struggles, with greater concern for individuals with heart conditions, drug intoxication, or implanted medical devices. Legal status varies by jurisdiction, with some places permitting civilian possession under restrictions and others banning or tightly regulating ownership and use. Training and use-of-force policies are common requirements for authorized users.
