We're told the Washington Wizards have told D.C. cops they have locker room surveillance video but are having trouble downloading it. The Geek Squad -- aka computer-savvy detectives -- are going to the Wizards organization today to help.
And get this -- a source connected with the investigation tells TMZ the Wizards have been "over cooperative" with cops -- as the source says, "almost as if they want Arenas to go down."
The source says "there is a better than 50/50 chance the U.S. Attorney will issue a felony arrest warrant against Arenas."
As for what caused the confrontation that allegedly triggered a gun standoff -- law enforcement tells TMZ it was all over a card game known as Bourré.
The NBA suspended Arenas indefinitely yesterday and, as we first reported, Arenas didn't have a license for the guns.
