This guy is right. They would decay in a matter of months, and not to mention, humans have too many natural predators. Think about it, a lion/tiger hunter, when attacked by the lion/tiger, they get absolutely mauled. Now zombies, there much, much, much weaker, so if they were being attacked by any carnivores medium sized predator, they will be ripped to pieces. It would be safe have any weapons, just in case.
A zombie apocalypse would be incredibly impossible.
