Actually, I'd probably load the first one from backup and let it out, all else being equal. But it'd be foolish to do that before finding out what the other ones have to say, and whether they might present stronger evidence.

(I say first, because the subsequent ones might be UFAI that have simply worked out that they're not first, but also because my human values places some weight on being first. And "all else being equal" means this is a meaningless tie-breaker, so I don't have to feel bad if it's somewhat sloppy, emotional reasoning. Especially since you're not a real FAI :))
