They won't deny it, they just ignore it. What's happening is that the terrorists are infiltrating an army into this country to attack us. When that happens the government is going to bring the hammer down on ALL of us. The government KNOWS what is happening and choses to ignore it.
Yep, if you recall the DHS info for a condition RED, they can close down roads and transportation as well as public and government facilities, stop banking/trading activity, pretty much shut the whole country down.
