I can almost guarantee that when former United States Homeland Security Secretary, Janet Napolitano, spoke of 'domestic terrorists' in her 2009 paper on domestic terrorists* these were not the ones she had in mind. Hers were more on the order of Tea Party types, conservatives, returning military, and anyone who voiced an opinion about the size of government or disagreed with the politics and aims of the POTUS, Barack Hussein Obama.
To the best of my knowledge the map you are looking at is not recent - that is, not current as of 2014, which means that as of this date, in Virginia specifically, there are at least 5 such training camps. This is not a myth. This is all too true; the government knows about them and my question is, since our government knows, why are they allowed to exist? This is the ENEMY training to kill us on our own soil.
