Say on the anniversary of 9-11 we had a LAX style terrorist times a thousand -- all at once killing as many random people as they can. With an unarmed population and no Israeli security to protect us the death toll would be insane.
Of course the FBI would report the thousands of isolated incidents were just a coincidence along with the date they all independently decided to "get despondent." And only those guys they had a file on would be counted as terrorists.
