TMZ Sports has obtained the police cam video of Jeremy Lane's DUI arrest -- which shows the ex-Seattle Seahawks star questioning why he was busted and then yelling in pain in the cop car.
Lane was initially stopped by the Washington State Patrol for doing 80 in a 60 mph zone on January 14. When cops pulled him over, Lane admitted to smoking weed several hours earlier.
In the video, Lane doesn't understand why he's being arrested since the breathalyzer shows his blood alcohol content was significantly under the legal limit.
