An anonymous reader writes: A debate has been raging recently over whether or not to equip police with body cameras so that instances of violence in the line of duty can be monitored. It's an important discussion to have, but we should also look at other technologies that could help provide hard data on gun incidents. A new paper was recently published in PLOS ONE about the use of wristband accelerometers to detect when the wearer has fired a gun. Study author and criminology professor Charles Loeffler said, "A gunshot is pretty distinctive. You're typically at rest because you're trying to aim, and in a split second, your hand, wrist, and arm experience an impulsive transfer of energy." Loeffler suggests a suite of sensors including GPS and the wristband accelerometer could be given to convicts as a requirement for their parole. Not only would this help with police response in case of recidivism, but it could provide additional deterrent to further crimes. It could also be helpful to police departments, both for accountability and for integration between the police and the courts.
