NSA--Tip of the Iceberg

The Attorney General has been commenting on the NSA eavesdropping and saying that only a "limited" number of Al Qaeda suspects were having their overseas to U.S. communications intercepted. That may be true but that is only the "tip" of the iceberg, with many more intercepts being made that aren't being mentioned or "explained". If only a few suspects are being intercepted why all the secrecy? Doesn't make sense. What makes sense is the old "dodge" of letting out a little "wrong-doing" at a time, as more and more is learned, thus lessening the bad effects of a sudden and total impact on the public.
The administration will propagandize, lie, hide, justify, block, obfuscate, distract, mislead, all they can to get out from this bad spot they are in. Claiming that it is "legal" is now their main "dodge" that helps to confuse the public into thinking "he only made a legal misjudgement", so it is ok to break the law. If they can't justify their actions based on a "legal mistake" they'll get around it by "changing" the law after-the-fact, thus "legalizing" their breaking the law, thus avoiding impeachment. If there wasn't lock-step unity in the Republican ranks the Congress would be calling for impeachment on two grounds--starting a war without real justification and transgressing the Fourth Amendment--both impeachable offenses in my view.
