State senators advanced police reform legislation its drafters said is wrought with "heartbreaking" compromise and vowed to "fight again" for provisions Gov. Charlie Baker rejected earlier this month. Senators voted 31-9 on Monday to approve an amended version of bill that allows the use of facial recognition technology, as demanded by Baker, and removes police training standards from civilian oversight. Both elements were among deal-breakers identified by Baker when he sent it back to lawmakers Dec. 10. The changes to the bill now go to the House for approval. A formal session is scheduled for Tuesday, without a calendar.
