Hmmm maybe they have some inside knowledge? Lots of unknown army experiments maybe they created zombies in a lab somewhere like in Resident Evil and
they're just anticipating the experiments escaping or the thing that causes the zombie-ism to get into the main population? Either way I'd take it
seriously.
The American people are the Zombie!
That what they intend to kill.
best way to kill a Zombie is a head shot.
take the brain out.
and the rest will eat the brain.
Zombie walk so slow?
just like Chinese vampires.
but they hop slow.
