One question, why are there gasoline and guns in a prison? Prison guards can't even carry night sticks around, so why would the prison have those more dangerous weapons?

Maybe a prison would have gasoline for a backup generator. I'd also assume a prison that had superpowered people in it was packing something a little heavier than nightsticks. I could be wrong, but I can't imagine that sort of prison not having either of those.

Awww Blacksam beat me to it. Even if they couldn't get into the armory, they can still kill the guards that have guns. Not to mention there's obviously something at work here, unless one of the prisoners is powering the nullification field and reanimating all those beasts, so they may have found a way to help arm the prisoners/catalyze the prisoners getting guns as well, but that's more conjecture than anything.
