I don't know. This is a state matter so I'd have to look it up in Florida state law. I've never been there, so I've had no reason to learn it.
I believe this is one of those cases where legal doesn't equal moral. It appears to me that this whole thing is absolutely legal under state law, while still being immoral. The law as written by the Florida legislature failed her.
Not good enough where life and death is concerned. Florida has laws concerning guardians and what "may be a conflict of interest". A person can not be appointed a guardian if they "may have a conflcit of interest". It follows that an appointed guardian with a conflcit of interest should be removed. The Florida Court of Appeals acknowledges that MS has a "conflcit of interest".
What is the remedy if the state comes into your house and removes your weapons absent cause if the State Supreme Court rules it lawful?
