The maker of Taser stun guns has advised law enforcement agencies to avoid hitting suspects in the chest, partly “to minimize controversy.” “Taser has long stood by the fact that our technology is not risk free and is often used during violent and dangerous confrontations,” Taser International spokesman Steve Tuttle said in a memo referring to an October 12 training bulletin. “The issuing of a preferred target zone is a prime example of training advice based on best practices and field results to minimize controversy, increase effectiveness and provide enhanced risk management,” he said.
