Cop at center of Michael Cox beating case fired over another case involving excessive use of force

The Globe reports (paid subscription required) on the firing of David C. Williams for putting a man in a prohibited choke hold during a North End traffic stop, then lying about it.

This is the second time Boston Police have fired Williams. The first time was after the beating of Michael Cox, an undercover cop whom other cops beat, allegedly because they thought he was a homicide suspect, in 1995. Williams won his job back on appeal; his lawyer says he plans to appeal the latest firing as well.
