IMO, I really don't see how a drug could make someone that delusional we're the person would actually eat off the face or any body part for that matter, then growl at the LEO and witness and continue eating on the person. Then takes a shot at them and it doesn't even phase the person so he continues to shoot. But you notice how they won't say that the way the officer had to put him down was to shoot him in the head! You know that guy was probably like omg it's a F@$*ING ZOMBIE!! It's starting and when he shot him the first time and it didn't do anything you know he was like ok, I gotta shoot him in the head to kill'em. But the news isn't gonna tell you that.
