From Guns.com:

Gun rights advocates are livid after Miami Beach Police on Sunday briefly detained a group of fishermen on a public pier over questions on their holstered handguns.

The anglers, members of Sunshine State gun rights group Florida Carry, are shown in a live-streamed video of the event being interviewed by responding officers who have their sidearms drawn. While the advocates, who were ultimately released after two hours, hold they were within their rights as state law allows for legal open carry while hunting or fishing, police feel they responded within guidelines.
