 But when it comes to arming its 1,700 sworn officers, Indianapolis PD jumped into the business of trading off old guns for new ones. I can't remember the last time that we've done this. It's been several years, but we sell them back to Glock. They give us a credit for whatever it is, and then they apply that to the next set of weapons, is my understanding. Chief Bailey says he would consider changing the policy if the community asked him to.
