Since the crime is a second degree misdeameanor that probably has never been prosecuted, it is highly unlikely that Michael Schiavo would remain in jail any longer than necessary to have his paltry bond posted for him. More than likely after being booked, he would be released on his own recognizance. Any effort to have removed as guardian would be before Greer who would see these tactics for the sham that they are and refuse to remove Michael Schiavo as guardian.
I sure open adultery has been prosecuted in Florida before, even if not often. And even if arresting Michael for criminal adultery ultimately fails to save Terri, why not try it anyway? If you're going to arrest people who are just trying to take water to Terri, why won't you arrest the man who is killing her for his own violations of Florida law? Why does he get a free pass? Because adultery is popular but saving people from murder by starvation is not?
