yeah, i think your friend is screwed. and the cops did mess up not getting your BAC, or his - so at least he's got a hope. gotta love cops, man, you just went through the most harrowing experience of your life and he's in your face calling you a liar. unfreakingbelievable.
on the bright side, the nose will heal and it looks like you won't have any major scars. and you get to live. i know how close you came, having been there twice before in my life. and you'll get over the image you had when you woke up, too.
