How many people would push a button if they were told it would blow up DC? A lot of those on both the left and the right....but they are not actively looking to blow it up.
I agree.
He had the ability to agree or not in steps along the way.
When he had the phone, he was told to push the button to kill, injure or maim hundreds, maybe thousands of people. When it did not go off, he was asked by the agents to step from the cab of the truck and try again to get a better signal.
He pressed the button a SECOND time. What more d we need?
