An Act relative to dangerousness hearings

This bill amends Massachusetts law to change pretrial detention rules for repeat offenders. It requires the state to seek pretrial detention (instead of release) if someone faces a second charge for specific offenses listed in the law, based solely on dangerousness. The provision directly affects individuals charged a second time with these offenses, shifting the state's burden to justify detention at the initial hearing. The key mechanism is a new rule allowing the commonwealth to move for detention under dangerousness grounds without needing additional evidence beyond the second offense.
