Wow, why are they even taking zombies seriously? They have no proof whatsoever that there will be such thing as zombies. The assumption that zombies will eat human brains and will attack people is not even a real theory; it's something that a guy came up with a long time ago and everyone just thought it was cool and they kept rolling with it, like werewolves and actually vampires (Not animals, but humans with fangs whose heart has stopped beating and, well you know the rest).
Anyway, if for some law defying reason zombies did exist and they somehow posed a threat against humanity, wouldn't they be easy to dispose of? I mean, they're dead, they're weak, they lack muscles or basic intelligence. Speaking of muscles, how would they be strong enough to push their coffin open and break free?
If for some other reason they possessed some sort of virus that turned out to be contagious and extremely deadly (Death within hours, zombie effects follow), then I assume it could only be passed on to someone with direct contact with the zombie, just like many sicknesses out there. So as long as we avoid them, which wouldn't be hard due to their speed (Remember, no muscles), then we're good.
As far as treating the thing? Well...HOW?! They're dead and rotten! Unless they can find a way to make someone's heart beat again, to give them vital organs, to regrow large amounts of muscle and skin and to fix their brain, then it's pretty much a lost cause. At any rate, why would you bring a rotten corpse back to life? Because that's the only cure there is for this...unless they're talking about making them civilized? Which, at any rate, who's to say they would be wild and violent? I mean, some animals are wild and violent but you don't see people killing them just because. Well...we do but not like zombies.
That's a lot of ifs but I find it funny and ridiculous that the government is seriously considering zombies a threat. If it's still a joke, well then joke's over, man. It officially stopped being funny.
