So basically...after reading through all 300 plus posts here, am I correct in asserting the main question as to TRUE legality is if the person being "tapped" is a US citizen or a foreign citizen?
The Left will have you think that your legal rights are being violated, while the Right will tell you that it's about preventing a dirty bomb from going off. I suspect that the person caught in a dirty bomb won't be so concerned about their rights after the blast, while the Right's problem is that successful prevention leads to complacence and second-guessing about whether the threat was real or not.
Also, I've noticed recently that the Left is deflecting the "Bill Clinton did it" argument by asking if that makes it okay for Bush to do it, too. It strikes me that there was a time when the Left would have called that a "precedent." Now, it's an excuse.

That is my understanding yes (actually U.S. Person not just citizen but you are essentially correct).
