Now there wasn't anything anti-American about what I said there, Doug.

One of the alleged snipers is a Muslim of some kind (though "I am God" suggests a very peculiar sort of Muslim). But I am sure for most people, especially those outside the USA (who are of course "most people") his primary identity is seen as that of being an American.

The danger in all this is that once people start seeing particular minorities of one sort or another as being "the enemy within" they risk setting in train a process that turns that into a reality, in a vicious circle.
