The death of a man in Palma The incident of a man being subdued with a Taser has sparked debate about the health risks associated with these weapons and when they should be used. It also raises a question related to the same event: Can a Taser kill someone? "Yes, but it's extremely rare. Most exposures are not fatal, although they are never completely risk-free," says public health expert Juan Carlos March, explaining that a Taser "is designed for self-defense, not as a tool for killing." However, March warns that a Taser discharge can be "very dangerous and can even cause death" in people with heart conditions, low muscle mass, the influence of drugs, or who are pregnant.
