It is funny how these types of events have been happening in clusters lately. There are so many cliches interwoven in these events, it's hard not to think that they haven't been choreographed to some extent. Seems they are trying to implicate tea party, militia and conservative and Christian types in all of these.
Of course, it almost always turns out to be the opposite, in fact.
