Boston Globe | Eyewitness accounts strongly suggest that MBTA Transit Police Officer Richard H. Donohue Jr. was shot and nearly killed by a fellow officer in Watertown April 19 during the hail of gunfire unleashed on Dzhokhar Tsarnaev as the suspected terrorist made a getaway in a carjacked sport utility vehicle. Donohue went down in the early-morning darkness during an extraordinary gunfight in which at least a dozen police ­officers from four departments exchanged up to 300 rounds of gunfire with Dzhokhar’s older brother, Tamerlan Tsarnaev. The Tsarnaevs also allegedly set off explosives, including a pressure cooker bomb similar to the ones used in the Boston Marathon bombings.

Suspecting that Hinton was looking to buy drugs from Lee, Detective Kevin Sawyer replied to the message, posing as Lee. With a series of text messages, he arranged to meet Hinton in the parking lot of a local grocery store—where Hinton was arrested and charged with attempted possession of heroin.

We have just learned about the true nature of Facebook's responses to subpoenas thanks to documents uncovered by the Boston Phoenix, an alternative weekly.
