Eastern Europe
It's supposed to be happening in Prague, right? And the mob was Russian, right?
So:
Why did they keep on talking Russian (well, their version of Russian, at least) if they wanted to remain hidden and control their terrorist operations from a safe place? And didn't bother to learn Czech? Not everybody in Czech Republic speaks or even knows Russian. Wouldn't that be a give-away, then?
It seems to me that this is another of those flicks that support the wrong view about Eastern Europe (it is not one country-one language place) and then gives people bad ideas and stereotypes about that part of the world.
