According to the Boston Globe, the Massachusetts State Police has begun arming troopers with Tasers. But civil rights groups, including the Lawyers’ Committee for Civil Rights, have expressed concerns:
“Trading one weapon for another weapon does not ensure we are properly training officers locally or statewide,” said Ivan Espinoza-Madrigal, executive director of the Lawyers Committee for Civil Rights and Economic Justice in Boston. “It’s difficult for me to applaud one weapon over another. Any use of force that could be avoided should be avoided.”
