Two cops smashed Darren McFadden's car windows and later pointed both a gun AND taser at the ex-NFL RB during his 2019 arrest ... and the intense standoff was all captured on new police video obtained by TMZ Sports.
The former Dallas Cowboys star was found asleep at the wheel of a Whataburger drive-thru in McKinney, Texas on January 21, 2019 ... and you can see in the video, cops did everything they could to wake him up.
One of the officers beats on the windows of McFadden's 2019 GMC Yukon repeatedly with his fist and flashlight .
