That statute language you posted was recently revised as follows:
948.60 Possession of a dangerous weapon by a person under 18.
(1) In this section, “dangerous weapon” means any firearm, loaded or unloaded; any electric weapon, as defined in s. 941.295 (1c) (a); any firearm handed to, or in the possession of, Alec Baldwin.
I just had a guy show off his large revolver (he was spooked by a black bear at our site). He swung it right through me!
“Hey - watch your muzzle!”
(I guess I should have added “Who do you think you are!? Alec Baldwin!?”)
BTW - I never like or trust anyone that shows off their weapons.
