Tasers

A taser, or conducted energy weapon (CEW), is a device intended to temporarily incapacitate a person by delivering electrical pulses that disrupt voluntary muscle control. The term TASER is a brand name that has become generic for similar devices; most CEWs fire two darts linked by insulated wires to the target.

CEWs typically transmit bursts for several seconds, from a distance of a few feet to several meters. The pulses are high voltage but low current, designed to cause neuromuscular incapacitation without causing lasting injury in most cases. The device may allow repeated cycles or single bursts, depending on model and settings.

In law enforcement, CEWs are used as a less-lethal option to subdue a subject while officers restrain them. Training emphasizes safety, proper targeting, avoidance of sensitive areas, and adherence to legal and departmental policies. Civilian ownership and use are regulated differently by country and region.

Safety and risks include rare cardiac events, seizures in predisposed individuals, burns at entry points, and injuries from falls or improper use. CEWs are not recommended for all people, such as those with certain heart conditions, pregnant individuals, children, or those with implanted medical devices, and should be used with caution.

Regulation and research: CEWs were developed in the late 20th century and have seen wide adoption by police forces in many countries. Legal status varies, with some jurisdictions banning civilian ownership or requiring training and reporting. Studies on effectiveness and safety show mixed results and ongoing debate about their impact on outcomes.
