My reading is they beat him so badly they had to put him in a stretcher. Is that right?

For comparison: a close friend suffers from tonic-clonic seizures. That's the kind you see in movies when they try to be dramating, violent shaking, foaming at the mouth. the whole nine yards. After waking up from a seizure like that he often acts rather single-mindedly towards a goal, turning violent if anything or anyone is in his way. A while back he had a seizure in public, it took 6 police officers to get him wrangled into the ambulance. This sort of significant personality change doesn't happen from a slight bump to the head. I wouldn't be surprised if the guy has a rather severe concussion.
So no. I don't think the adult man frantically mumbling "I gotta get home, I gotta get home, I gotta get home" with a bloodied face is fine by any stretch of the imagination. In fact I reckon the only reason he managed to get back on the plane is because of, to put it bluntly, retard strength caused by a serious knock to the brain.
