They keep a lot of their more heavy duty equipment down at Quantico so it's possible they are simply checking things to make sure nothing unusual has happened/will happen that might make passage to DC in case of an emergency difficult.
Although the earliest news indicated the 14th street bridge would be closed to ALL traffic, they now intend to permit pedestrians and will allocate a full highway lane for that purpose. I believe automobiles will be prohibited from like 4AM to 4PM ~ they announcements have changed the closure times enough I doubt they really know.
We are getting far greater than normal helicopter traffic in the corridor and I've heard a couple of fighter jets tuning up ~ kind of like after 9/11.
It’s been raised a number of times by different people but again it is worth repeating. Any violence would be a bad thing for America. Beyond the criminal aspect (it is WRONG), it also introduces a factor of chaos and anarchy into our nation. It gives the Left opportunity to demonize the Right (justly or unjustly) and makes a martyr of the victim.
We’ve already seen how history has been rewritten to suggest that JFK was really a saint and was planning to end the Vietnam war. No one has any unanswered questions about how Jimmy Carter “would have” ended his first (and only) term as president.
I want Obama, Biden, et al to outlive their elected terms to office. Exposed as inept, inexperienced, unqualified, the media complict in their 2008 PR scam, and unsuccessful in implementing socialized medicine and other policies that are wrong for America. I just hope they don’t screw up things too badly and that our nation does not suffer as a result.
