Well, in that case, they government would have to be conspiring with George Romero, not a very pro-government type of guy. But if you’re worried, keep a good supply of provisions laid up along with guns and plenty of ammunition. As regards the provisions, that’s usually a good idea anyway, both in terms of preparedness and as a financial hedge against inflation.
You do realize that this is mostly tongue in cheek, right? Still, the number and variety of Zombie movies does seem a little strange to me—its much bigger than Mr. Romero. If you wanted to prep the public for something without creating an obvious panic, this would be the smart way to do it.
Also, wear tight-fitting clothes, keep your hair cut short and remember, most of all, "you don't have the reload a machete". :)
