I'm hearing that both men were naked. Hmmm. weirder and weirder.
On the zombie side, this should be an alert to all would be survivors. The thing to watch isn't the dead guy, but the survivor. we would need to note the hospital he went and to watch for either a news blackout, or another grisly murder after the victim turned.
Thank goodness that movies are just that. but if flesh eating zombies were the result of a disease, we conspirator's would all be on the alert, cars gassed up, bug out packs at the ready, families sent to the hills for the weekend...
