The cop may have been attacked by a single zombie, it didn't have to be a herd of them. It is unlikely he would be completely devoured, because that isn't what happens to most people. Unless they get swarmed, a little bit of them gets eaten and the rest is left to reanimate. If the zombies completely devoured most of their victims, there wouldn't have been a zombie apocalypse. Their numbers wouldn't have multiplied to the point where civilization collapses.
The cop may have also drug himself out of the vehicle. He was conscious when he was attacked, because Lee hears him screaming.
