You aren't the only one. Was it just a coincidence that the feds raided that group in Portland the day after the shootings began in DC? They were conducting small arms training and had been suspected of training in camps in Afghanistan (if my memory serves me right). Now they are saying that they had links to the camp in Alabama? When they raided the place (in Portland) they found one empty .223 shell casing but no rifles that fire a .223 round.
If my hunches have been correct, I guess they didn't want to panic the sheeple.
