I have mixed feelings. I would like the right to do it, and then decide where and when. To me, open carry is mostly a political statement.
It would be nice to not have to worry about being a felon just because your cover garment comes open or rides up.
But, there is a definite tactical disadvantage. I will go one further too. When someone that doesn't like you wants to ruin your day, they call the cops and say (lie) you pointed your Glock 19 at them and threatened them. Cops stop you and you have a Glock 19. Your word against his -- sometimes you lose the probable cause game.
This is one of the reasons you don't tell people you carry, and you don't tell them what you carry. When its out in the open, it just makes it that much easier to set you up and seem credible.
That being said -- I will support the movement in Florida and make my own decisions as to when it is appropriate.
