Live manhunt, here. It's sort-of addictive, especially with the local accents: "They're bringin' sammiches to the troopahs." "We have a small cah, a Honder here heading up Bahston Boulevahd." Mostly Irish, some Italian, all Bahston.
The professionalism is impressive, but not surprising. They shut down the entire city, and Watertown, to find this bad guy, but have obviously not found him yet. Any accomplices, I am sure, are being sought off radio.
