School of Hard Knocks

Donnie Wahlberg catches a case involving a school shooting at a local inner city high school where the principal Ernie Hudson is at his wit's end. Later on a special ed teacher Flor De Lis Perez is assaulted in the high school as part of a gang initiation. That part of the story nearly ends in a tragedy.

Bridget Moynahan is working on an organized crime case and it saddens her that an old colleague and friend Raphael Sbarge now in private practice has himself hip deep in corruption with a gang that shoots its way out of trouble.

But on the brighter side Tom Selleck as police commissioner gets to go toe to toe with Governor David Zayas when one of the Governor's staff is an innocent bystander in a shooting. The Grand Jury clears the officer, so does the police review board. Still Zayas wants the officer's shield and is threatening to sic his Attorney General on the NYPD.

Selleck finds some ammunition and has no hesitation using a little hardball to protect his department. That's what really makes this episode worth seeing.
