The info is available. What is done with the info is when the boundaries of ethical conduct can be breached.
I understand that. But again, the more justification we allow the government, especially on privacy issues, the slippery that slope becomes. At the very least, with the warrantless wiretap issue, there should be Congressional oversight, or oversight that doesn't come from the Executive Branch. There is oversight with FISA, in the form of Federal Judges, but once you remove them from the equation with allowing wiretaps without warrants, there isn't any oversight. And actions without oversight, especially in government (and I don't give a flying squirrel if it's Dem, Rep, or Ross Perot) isn't a good thing. It tends to end badly for one party or another.
That's beside the fact that this breach took two months to come to light. Yes, as you said, the breach probably isn't important. That said, it has the potential to become important. And breaches, whether it's passports, wiretaps, credit card records, phone records, or my Columbia House CD club, are inherently bad. They destroy trust and credibility.
