TMZ Sports has obtained video of Barry Cofield's DUI arrest ... and the scene is intense -- with cops drawing their guns and demanding the ex-Giants DL to get out of the car.
"Get out of the car!" one officer screams ... "Get out of the car now! Get out of the car! Get out of the car or we'll shoot! Get out of the car now!"
It all went down last July when the former Super Bowl champion allegedly led cops on a wild police chase after they found him asleep at the wheel of his Cadillac Escalade around 2:40 AM.
