This reporter did not ask these questions:
What if the FBI had booted them out of the country when they interviewed them?
What if we simply automatically deported anyone with a green card that breaks the law?
What if we never allowed visas for anyone known to come from a country that sponsors terroism or is a breeding ground for them?
What if there had been a ban on pressure cookers?
What concerns me is that they will push through a ban on gunpowder. And maybe that was the whole point in letting these bastards blow up people.
