C for the leak
(or give him truth serum again)
about the scientist:
"I don't think we need to do that, we will just make you sign more papers giving harsh punishment if you leak this just for security, we know that you don't want to a fake rebel organization getting the credits for the cherubs, but really, we already passed the line in this one, we must remedy this and put a note to not do something like this again, our aristocracy already pushed some people to become rebels and try to get a anarchy, and we aren't talking about a good utopia here, but here, as we are already here and you are being granted an audience use this chance. Is there something else you want? Our laboratory's don't has that many future projects for now, is there something that our scientists are eager to test?"
And brainwashing will revert their thoughts about the events, really, it's nice to have some extra in stock for situations like these to put drink on it, but i think it will be weird to think:
"Oh hey i felt that this shit about fake rebels is very nice but i came here to convince you guys to stop it"
About the marksman thing, besides doing this we should give better options of non-lethal ammo for our Elite Mooks, it will not KILL them, but will slow them down give problems on the long-run and make the odds against them worse till the point where there is no excuse to live and the plot armor breaks.
Sleep/paralises poison
Electric bullets (and a good aim to destroy EQUIPMENT)
Those anti-adantesite lasers
Invasive Tracker Device (grab the meat and track the victim, they will only get it off hurting themselves badly or amputating the part)
