re: probable cause
There is "probable cause" up the wazoo in this case. Jefferson has been stonewalling subpoena requests for cooperation for a long time. He was caught on video tape taking a bribe. Every proper warrant and judicial step was taken first.
BTW, in hindsight, his drafting of rescue forces after Katrina to help him get a couple of "important boxes" out of his house takes on a whole new interest.
There is nothing reflexive about my opinion here. You might want to ask yourself if there's something reflexive about yours.
