Must be bad if the FISA court whines about it.

FISA court was set up to "oversee" the intelligence agencies snooping, wiretapping, email intercepting, and credit card record requests.  It's secret, so secret that we don't know their decisions, their judge[s], or their rules.  Over the years FISA has acted as a rubber stamp on the intelligence agencies requests to snoop on everybody.  99% of requests to snoop get approved. 
   Now we have NSA lawyers admitting to the FISA court that NSA has not complied with some secret rules about searching the national secret database of every phone call made in the country.  It must have been pretty bad because the normally doormat FISA court expressed unhappiness about it.  They didn't have the stones to hold anyone in contempt of court, or denounce them by name, all they did was whine about it.  But for a rubber stamp court,  expressing unhappiness with an intelligence service is VERY unusual.  Must have been something really bad.
