I'm pretty sure that it is an homage to the X-Factor Investigations cover.
My first thought was that X-Factor were trapped inside a government building with bars, like they felt trapped by the government, but that doesn't really make sense.
So I guess that they are just looking outside a government window. I would doubt that the window shades or whatever they are are reinforced bars, seeing as it is Havok bending them, and not Frenzy.
