Complete disbelief? I thought it was common knowledge that the NSA spies on everyone and has spies working or intercepting shipments from most of the major tech manufacturers in the world.

The NSA's typical practices aren't generally thought to include encouraging domestic criminal groups to steal sizable quantities of money from foreign banks. Or sitting idly by as it happens on a regular basis.

We expect the NSA to be compromising foreign systems. We don't expect them to be doing this with them.

I'm pretty sure the NSA isn't hacking banks to steal a few million dollars, considering their budget.
