I have to say I didn't like the whole movie. There's suspension of disbelief and then there's this movie where you have a bunch of scenes tacked together with little logic or coherence in the story. I think the part about chopping off her arm was just the tip of the iceberg as far as ridiculousness and stupidity go in this movie. I love the part where he is going to jail and just blasts her away in the court house (where nobody except his old colleagues of course see it for some magical reason) in broad daylight. Yeah bro we were sending you to jail, but now that you blew her to smithereens we changed our mind and have this full pardon and medal for heroism.

Well, they kinda set that up. They wanted revenge on her for all the cops she had killed and they knew he would get goaded into reacting. The part that is REAL BS is that they were like, "Oh yeah, your past sins forgiven. No jail time for you." Now that WAS BS. Hero commendation? Maybe, but that don't mean you ain't going to jail for your crimes.

I thought it was a very good movie. But Lena Olin's performance alone makes it worth watching.

He shot her in the arm so she lost it. She was a hit man for the guy so I'm guessing they were friends behind his back. With her dead there was no one to testify. They made him the deal. Or else it was part of his deal for the beginning.
