Arenas Standoff -- Cops Want Players' Faces

According to sources, cops want to see how Gilbert Arenas' teammates reacted to his Christmas Eve gun standoff with Javaris Crittenton -- and they're hoping to see the players' faces on one key surveillance camera.

We're told the crucial camera angle is just outside the Washington Wizards locker room, and cops want to see the reactions of players who left after the showdown.

Our sources say cops are still trying to download the video from the surveillance system.

Team officials tell us there is no video inside the locker room. Translation -- don't hold your breath for a money shot of the armed incident.
