I actually like the idea of the Modern Inquisition, mostly because with all of the monitoring these days the Jyhad would stick out just as much as a Jihad to people who investigate things. The idea that some of the glowies would put 2+2 together and realize there's someone out there up to no good, and in fact have been for god knows how long, adds to the plausibility.
Naturally the execution of that simple concept was done as terribly as everything else they've done. Hell, their book on the London guys has the Sikh running the show face constant discrimination from his co-workers A Sikh, discriminated against in London! Ah, I guess that's the price of importing all those Musl- no wait, the guy with low-level PTSD from Afghanistan associates his boss with the goat fuckers that were trying to blow him up.
