Fairly reasonable for law enforcement to seize firearms/ammo based on a claim of a threat? Then the accused has to go before a judge to prove they’re not a threat? Fairly reasonable to prohibit an adult to purchase a firearm? Ever hear of the Constitution? I’d hate to hear your definition of draconian.
States are sovereign outside expressed U.S. Constitutional limits (the 2nd amendment is pointed directly at the feds).
Florida is not constitutionally prohibited from passing this law, but I’m willing to bet the virtual tyrannical discretion given to the police violates the Florida State Constitution.
