tasing

Tasing refers to the use of a conducted energy device (CED) to apply an electrical discharge to a person. Modern CEDs typically eject two small darts connected by insulated electrodes and deliver a high-voltage, low-current pulse intended to disrupt voluntary muscle control. The resulting muscle contractions and sensory effects often produce temporary incapacitation, with effects lasting from a few seconds to several minutes; some devices also offer close-contact modes. The electrical exposure is usually localized to the body region contacted by the probes, though secondary injuries from falls or contact with hazards can occur.

Development and use:

Conducted-energy devices were developed to allow law enforcement to restrain or incapacitate a subject with a lower risk of lethal injury compared with firearms. The most widely known consumer and professional models have been marketed under brand names but are collectively referred to as tasers. The acronym TASER stands for Thomas A. Swift’s Electric Rifle. Since the 1990s, CEDs have been deployed by police in many countries, with variations in policy, training, and permitted use. In civilian contexts, legal restrictions and training requirements vary by jurisdiction.

Safety, risks and controversies:

CEDs are considered less-lethal but not non-lethal. Adverse effects can include local burns or puncture wounds at probe sites, transient pain, disorientation, or respiratory or cardiac effects in susceptible individuals. People with heart conditions, implanted cardiac devices, or those under the influence of drugs may be at higher risk. Serious injuries and rare deaths have been reported, often in combination with other factors such as falls, underlying illness, or prolonged struggle. Ongoing research continues to assess safety, effectiveness, and appropriate use guidelines.
