Criminal Justice

This bill amends Massachusetts law to prohibit the manufacture, sale, and operation of robotic devices equipped with weapons, while allowing exceptions for law enforcement, the military, and specific testing or educational uses. It establishes strict penalties for violating these rules, including mandatory prison sentences without the possibility of probation or parole, and criminalizes using such robots to threaten, harass, or physically restrain individuals. Additionally, the legislation requires law enforcement agencies to obtain a warrant before deploying armed robots on private property or for surveillance, mandates quarterly public reporting on their use, and grants individuals the right to sue for damages if the law is violated.

This bill (H 4645, now Chapter 79 of the Acts of 2025) increases penalties for assaulting public transit workers while they are on duty. It makes it a crime to commit assault and battery - including using bodily substances like blood or saliva - against a transit worker performing their job, punishable by 90 days to 2.5 years in jail or fines of $500 to $5,000. The law specifically defines "bodily substance" to include human secretions such as saliva, urine, or feces. It directly affects transit workers by strengthening legal protections during their work. The bill was enacted in late 2025 after passing both legislative chambers and receiving the Governor’s signature.
