Judging the System

After the murder of Yarmouth police officer Sean Gannon in April, the NBC10 Boston Investigators took the lead immediately, examining the system that let yet another violent criminal out on the streets. In the murders of the last four police officers, we uncovered a Massachusetts system now in question with the governor’s office.

We repeatedly found judges who had the chance to keep the eventual shooters behind bars, but instead released them. In a rare opportunity, three Massachusetts police chiefs who lost officers sit down together with our team calling for change: “Somebody help us!”

In Judging the System, the NBC10 Boston Investigators question why career criminals keep being let go and what will it take to stop it.
