Our plan is natl guard in riot gear? DoubtfulThere are quite a few terrorist organizations just across the border in Canada. National Guard troops train to deploy and serve in CONUS their business is what happens on our soil. If a terrorist attack does happen in NY again you will be happy to know that there is a plan to help deal with the concequences and that people have been trained to contain the problems associated with it.
Think LA after the Rodney King Verdict, the National Guard was called out to contain the violence. The same could happen after a terrorist attack, there are many scenarios that containment would be needed, such as a biological attack or chemical/radiological attack to keep it from being spread to neighboring counties.Our plan is natl guard in riot gear?

99% sure sounds like civil unrest training.
Edit: you are eluding to civil unrest due to a terrorist attack? Didn't happen in NYC after 9/11.
