those people can still be a liability when the shit hits the fan. if they're safely sequestered somewhere providing support statesaide, housed in some barracks. that'd be safe. can you imagine lisa going batshit crazy, needing to be thrown down the stairs when no one has time to do that? no, that's unsafe.
I'd be ok with lisa being surrounded by people with guns tbh, one wrong move and she's gone no big whoop
