Yes, that's right, some racist psycho murdered a bunch of people in Texas, so it's time to "take the gloves off" again, pass some new kind of Patriot Act, further curtail our civil liberties, and generally whip the public up into a mass hysteria over "white supremacist terrorism."
The New York Times Editorial Board is already hard at work on that front. In a lengthy op-ed that ran last Sunday, "We Have a White Nationalist Terrorist Problem," the Board proposes that we would all be safer if the government — but presumably not the current government — could arbitrarily deem people "terrorists," or "potential terrorists," or "terrorist sympathizers," regardless of whether they have any connection to any actual terrorist groups, and ... well, here's what the Editorial Board has in mind.
"The resources of the American government and its international allies would mobilize without delay. The awesome power of the state would work tirelessly to deny future terrorists access to weaponry, money and forums to spread their ideology. The movement would be infiltrated by spies and informants. Its financiers would face sanctions. Places of congregation would be surveilled. Those who gave aid or comfort to terrorists would be prosecuted."
Comment: It's difficult to believe they had so many specialists in close proximity to danger, assuming they were well aware of the risks - unless something happened that caught them completely by surprise.
US media and govt figures are certain that what is being tested at that site are the paradigm-breaking nuclear-powered cruise missiles, first announced to the world in Putin's March 1st 'state of the union' address last year. They could be bluffing, but they may be close to the mark.
This was likely the result of sabotage. It's all-systems-go in Russia these days to produce a target level of advanced missile capability, and according to a schedule. Anything to derail that potentially helps the Americans catch up.
