I have to wonder the same thing about the Iranian mosque investigation. It is common in the middle east to operate money transfers informally through the mosques. The fact that some people transferred money back to Iran through the mosques is not, of itself, evidence of anything wrong.
And the idea that the Iranian A-bomb effort is being funded in any direct way by contributions from mosque attendees rather than through its far more secure and secret miltary budget is ridiculous. Odd that this strange (and going nowhere) story breaks today. It's an attempt to look tough while wimping out on other things.
And note....there were NO indictments announced today, so why make the announcement.
