I've said it from the beginning and frankly I don't think people realize how true it is. They were incredibly lucky that a mob of people actively attacking congress wasn't shot dead to a man.
Not that I think that would have actually been the best outcome, frankly I think that would have started an outright civil war and nobody wins that (not to mention that many innocent people almost certainly would have been caught up in it in the moment itself. But it very, very easily could have been.
