Last month, a lone gunman shot and killed Dr. Michael Davidson at Brigham and Women’s Hospital in Boston. By all accounts, Davidson was an outstanding doctor, husband and father of three with a fourth child on the way. No one saw it coming.

The recent incidents making the news in our cities across the country have led to calls for body cameras and alternatives that will de-escalate violence that many time ends in injury or death. Lack of knowledge of current technologies that can address these important issues more often than not leaves questions unanswered.

The call for safety must not just address violence in the streets but must also concentrate on that which occurs in schools, hospitals, shopping malls, stadiums, the workplace, and any venue where people gather. While the current focus is quite narrow, the solutions offered must be broad enough to target all violence.
