OC is just a matter of freedom and trust. That is all, nothing more and nothing less. Is this a free country: or not? Does the government trust it's citizens: or not? Restricting method of carry is an infringment on your right to keep and bear arms, if you personally understand it that way: or not.
If you wish to carry concealed, that is fine, but what if your "concealed" weapon inadvertantly becomes visible? In FL that is a no no.
After a statement like that in the OP from a LEO, I would be for working very hard to see that the person making the statement be removed from his position. He is unsafe, just like the NY MTA cop that just shot another cop, just because he saw a man with a "gun". A slung rifle at that.
