Movie about Murdered Husband and wife going bananas in NYC

[baguafox]

I cannot for the life of me remember the name (or any actresses/actors) of a movie I saw around 2007-2008 about a couple walking through Central Park. During the stroll they enter a tunnel, and are attacked by a bunch of gangsters who end up killing the husband and hospitalizing the wife. For a bit the protagonist is afraid to leave her house after the incident, but finally after getting over her fears she goes completely bananas and starts murdering gangsters around the city. I remember a scene in the subway where she shoots some guys, and I think at the end she tracks down the killers of her husband in the hood. PLEASE help.. I am going nutz over this.

This was The Brave One (2007) with Jodie Foster and Terrence Howard.
