If they were enthralled the US justice system will eat them alive for stuff they arent really culpable for; the justice system isnt set up to account for magical mind control as a factor.
Thats something I think would weigh on Molly's mind.
But I have concerns about sending people who may or may not have Outsider-attention to the Brass Courts.
Genuinely torn here.
Yeah, if they've been touched enough to look for that could get bad. At minimum the cult should have all their true names, which you can do quite a bit with.
I think it's worth considering that ultimately innocent and not being a danger to themselves or others are different things. After getting hit this hard by a death cult it's probably genuinely unsafe for them to be unattended.
Disappearing them won't really help the situation, it'll just make it impossible for them to reconnect on any level with their family and friends from before the cult.
This is essentially what insanity pleas are for - if they weren't in their right minds they shouldn't be punished, but they need round the clock help to ensure they don't kill themselves or someone else the next time they have an episode. Which is a concern even if the immediate control is broken because mind magic is a bitch like that.
We have the money for expensive lawyers and connections with feds who know the score. Call the Library now and lay it out for them, along with our strong desire to see this handled justly even if the law hasn't caught up with the circumstances yet.
If they play ball then any actual thralls end up in some kind of care, hopefully somewhere that can actually help a little that the Library has access to*. If they don't, or start screwing up, we have other perfectly palatable options.
The white council for example has to have some really, really, good legal resources built over centuries of activity. They're also perfectly willing to spend significant amounts of mortal money for supernatural stuff and clean up the details on their own.
We could trade them all sorts of things that simply can't be bought but are trivial for us to acquire in exchange for the really scary sort of lawyers.
It helps that this situation is so weird and that nobody died in this attack. There aren't going to be families on tv howling for blood or anything.
* The inquisition had one for the Ants so I don't see why the feds couldn't. Even with no talents on staff just having people who know the basic details would help a lot.
