That shootout was crazy and while I'd normally roll my eyes a bit at every single cop getting wasted while the three main detectives didn't get a scratch, there were enough awesome sequences during that scene to make up for it.
The two that come to mind are when the old, lazy detective that was just trying to coast towards his pension check ends up taking a bullet to the forehead. Then, when Ani runs out of ammo and pulls out that blade to slash the last gunman right before he gets gunned down. I'm a little disappointed that she didn't get the chance, but I'm thinking that it was probably foreshadowing something badass that she's going to end up doing later on. Chick is ballsy
