CommonWealth Magazine's Jack Sullivantalked about police use of deadly force in Massachusetts. Police in Massachusetts killed suspects in 73 cases over 12 years. The review process for those cases is opaque — fellow police investigate incidents of deadly force, and district attorneys who often work hand-in-hand with police are left to decide whether to prosecute.

Nobody questions the fact that an officer's job is dangerous, and that suspects wielding weapons — including higher-powered weapons than what the cops have — put lives immediately in danger.

But Jim Braude and Margery Eagan talked to Sullivan about how to make the follow-up to deadly-force incidents more transparent. Sullivan's CommonWealth Magazine piece is called "Clearing the Cops."
