[JURIST] Gun control advocates are set to start an intensive media campaign to alert travelers about a new Florida law that allows people to respond to threats by using guns at home or in public [JURIST report; SB 436 text]. The NRA-supported "force with force" or (to opponents) "shoot first" law formally takes effect Saturday. Peter Hamm of the Brady Campaign to Prevent Gun Violence [advocacy website] says the new law poses a risk for tourists coming into Florida because they are unaware that this new law exists, hypothesizing that a simple road rage dispute could end up in the death of a tourist. Michigan gun-control advocates have been campaigning to prevent a similar "force with force" bill [JURIST report] being passed in their state. The South Florida Sun-Sentinel has local coverage.
