I've talked with several people online who have cancelled vacations in Florida as a protest about the TM case. Some of them have written the Governor telling him WHY they will not be visiting Florida as long as the Stand Your Ground law is still in effect.
Florida has always been very sensitive to issues that will affect tourism since it is such a large part of the state's economy. They can't afford to have tourists too afraid to visit.
Years ago, after the German tourists were killed at a rest stop, Florida added security at the interstate rest stops that continues to this day - the stops where there is no security are locked at night.
The Florida tourism industry is very powerful and if they push to get rid of the Stand Your Ground law, it could be gone by the end of the next session of the legislature no matter what the NRA says.
IMO, JMO, etc.
