I doubt that he could have found grounds (in a legal sense) to do so, much as I would have liked. He would have acted if he and his legal advisors thought it was possible. Judges can be impeached by the legislature and removed only by impeachment. They cannot simply be fired by the executive leaders of the state or the country. Sorry, but I just can't figure out how many of you think he was remiss. He did push the bill to save her through the FL legislature and signed it immediately.
Jeb tried, I will give him that, but I would have put Greer behind bars for as long as I could have on any charge at all. I am pretty sure that LE can throw anyone in jail for at least 48 hrs without any charges what so ever. Long enought to get a temporary Judge to rule to revive Terri.
