The Reality of the Situation *Spoilers*
Ok, so you've got this Zombie Apocalypse thing going on. You discover that a stop gap measure is an anti-virus that holds "The Turning" at bay by synthesizing it from the spinal fluid from a zombie (we'll just go with that term).
Now, at some point, a statistician that works for an alphabet agency figures out that with the dwindling supply of "donors" comes a dwindling supply of anti-virus. He/she kicks that upstairs to the boss who passes it around a committee and it's decided.
Farm them. Keep a ready supply of the zombies on tap, so to speak, voila! Status Quo. As the zombies reduce in numbers, naturally, then there's a steady supply of violent criminals that could be transferred to a more "secure" facility where they can take part in "experimental" drug testing (zombie spinal fluid) in exchange for... well, whatever B.S. they want to feed them. Or just simply strap them down and do it.
Two birds with one stone!
Oh. And tax the anti-virus. Like everything else in life. 💲
