See this makes me think of a great set up for a player crew instead of adversaries. Imagining a black-ops sanctioned team composed of a sorcerer or two, you have room for some pure mortal or adjusted mortal overseers, and of course Malivotti's WCVs (love that idea), or whatever else you want and you wind up with a group that designed to go around the country handling problems. Hell, maybe they have a combat chaplain from the Vatican who is there Lore expert, even. Think Father Rourke from "The Warrior" on steroids. Perhaps if they need planes or something for the gifted folks those people could sit in a special section of the plane warded by a closed circle? The whole organization understands that the higher ups think that they're eccentrics so the reports are sanitized when they leave the team, thus making some of the vanilla authorities more okay with this odd crew that gets it done.
Of course the organization is vested in ensuring that their team does what they want them to do, including kill on command, so any sorcerer would also have to have Lawbreaker (1st), and probably at least the organization knows about the White Council and takes pains to stay out of their way.
As Harry says in one of the stories somewhere, if the government every became officially aware of the supernatural in a big way, things would get very ugly, very fast. Well this here's the first step to getting ugly fast. A whole organization of sanctioned government warlocks is going to drive even the liberals on the Council totally apeshit, especially if a branch of the Church (even an expat one) thinks these folks are okay...
