He didn’t let go of the inside of the vehicle/the occupant after he smashed the window, reached into the vehicle to try to unlock the car, and the occupant started driving away. He received some pretty gnarly cuts to his wrists from the window he shattered, from what I read. I’ll try to find it.
ETA: “The agent got his arm stuck in the window of a vehicle of a driver who was fleeing arrest on an immigration violation, and was dragged roughly 100 yards down a street before he was knocked free. During the incident, the agent fired his Taser and prongs struck the driver but did not incapacitate him, according to prosecutors….
The officer’s right arm was bleeding, and an FBI agent applied a tourniquet. Eventually, he was transported to a hospital, where he received more than 50 stitches. Prosecutors said he had “suffered multiple large cuts, and abrasions to his knee, elbow, and face.“
Federal court documents show the agent who shot Good was seriously injured in a prior incident in June in which he used force against the driver of another moving vehicle in Bloomington, Minnesota.
