Sounds like a classic black bag operation.
Fighting terrorists is a messy business.
I'm reminded of the movie Grosse Pointe Blank, where John Cusack's character utters the following phrase:
When I left, I joined the army, and when I took the service exam my psych profile fit a certain... moral flexibility would be the only way to describe it... and I was loaned out to a CIA-sponsored program, and we sort of found each other. That's how it works.
In a perfect world, people wouldn't get drugged and suffocated in hotel rooms, but we don't live in a perfect world. And this approach seems extraordinarily preferable to Predator drones killing innocent women and children along with the intended target.
If I show up at your door, chances are you did something to bring me there.
