That was only after a we did all the heavy lifting and the existing Supernatural element had no resistance it's really difficult to say that they're super effective when the only time they're effective is after we do all of the work. Never mind the fact that the flesh trading you're talking about was murder most foul not actually flesh trade as most would understand it.
Which means they were just doing an actually good job as law enforcement which they should have been doing in the first place they should have needed us to clean house first. It's not like the trafficking in Vegas is a secret on the whole
Vegas was a city mortal authorities never had control over; it was a city state founded by a major supernatural which pretended to be part of the rest of the country.
The Marcone is not the smartest man in the country; if he can do it then so can a bigger, stronger, and more clued in organization. They just need opportunity and reason to believe it'll stick. That's what our backing would give them.
You do know that Dresden is a ranking member of a extrajudicial International murder cult, right no matter what reasoning they dress it up as every member of the white Council that is involved in the extra judicial killing of anyone in any country is a murderer and aiding and abetting murder in every jurisdiction. The fact that he is perceived as working for Marcone is just icing on the cake of actually being an international criminal.
Ethics of it aside, being a regular murderous cultist of the white council wouldn't have stopped them from going to him for help. It's explicitly canon that his involvement with Marcone is what stopped the Ordo in particular and the minor talent community at large from talking to him at that time.
Well the only other alternatives is to do nothing because some portions of the thread doesn't want to actually address any systemic issue or interact with the real world in any particular way so it's Marcone or no one because yet again the white court has its hooks in the actual federal government and the Library of Congress is just a tendril of the federal government and not actually an enforcement Branch at that. So you can trade the hypothetical perfect good that doesn't actually help anyone as it never comes or you can have an imperfect solution that actually helps people immediately.
My proposal isn't to do nothing.
We're going to Vegas this turn, while we're there we can advance our agenda with strategic real estate purchases and arranging to have our minions help a little from their new fortresses.
Why do you think that Molly utilizing Marcone's people to help keep order in the supernatural world, essentially turning them into warden auxiliaries would be perceived so negatively by political operators? Why is he worse, in terms of cost/benefit analysis, than White Court (international slave trade, almost certainly drug trade, blackmail on the large scale, extrajudicial killings of civilians), White Council (international human trafficking, extrajudicial killings, smuggling), Jade Dogs (a local gang, some members of which were cannibals)?
Both perceptions matter, and both see him as bad for different reasons.
The people on the ground see the nastier sort of criminal and won't be happy with that. The political system/government sees an organized effort that undermines it by existing.
The problem with your cross comparisons here is that we don't have the same type of relationship with those other entities and the calculation you're performing doesn't hit the points that matter. The people who do care about the harm being caused aren't going to accept the argument "we're only as bad as the other guys".
Do you not see a difference between agreeing not to go to war with someone and actively expanding a criminal enterprise?
Focus how? What do you propose we do about those on the scale of Chicago and Illinois?
Paranet for a start, and especially Ordo membership because it carries immunity to whamp attack as a membership bonus.
Help the good elements of the authorities succeed so they can push out the bad ones with material and informational support.
Perhaps something like starting a megacorp and hiring talents as consultants as a means of moving money and people around when needed.
We even have a film studio, which is an excellent excuse for very weird research consultants. Some random weregator needs out of backwoods Florida? Hired as a local expert for firm research and paid a bonus to fly out to our offices. Local ectomancer needs help keeping the region's ghosts calm? We ship them some reagents/tools in a work from home onboarding package.
More immediately, use our trip to Vegas to help expand the reach of law enforcement.
