Objectively no threat? How do you know? From the article? I didn't see an objective threat assessment in there.

How do you know with enough certainty to bet someone's life on it? Did the other guy pose an actual threat before he caught a bus to New York?

Given what just happened - and, as the sheriff mentioned, how the country has reacted - the default response is not to assume that there is no threat. I'm not sure that it should be.
