How hard is it to get a friggen wire tap?
I heard that, over the years, the special court has only denied about 5 out of 17,000 wiretap requests.
If the Bush Administration had been smart, it would have made the requests.
As for the exigent circumstances argument, there is a specific procedure for going in after the fact.
This was pure stupidity and/or hubris on the part of the Bush Administration.
