If "legal", don't worry....
I have carry permits for several states as a requirement for my line of work. I've had numerous encounters with LEO in various states while I was legally carrying. For the most part, the LEO have always been professional and courteous. At the beginning of the encounter, I provide the LEO with my identification and carry permit for that state. I'm usually asked a few questions and I'm sent off on my way. In one circumstance I had a problem with a LEO in AZ. He was thought that I needed to be a FL resident for the permit to be valid in AZ. This happened at a DUI roadblock. I don't drink, don't use any other "substances", no prescription drugs, etc., so no need to worry about being "under the influence" of anything other than my Starbuck's coffee or a few cans of Diet Pepsi. In any case, I was the unlucky "random" car that was pulled over. Following my SOP with any traffic stop, I pulled over where instructed, turned on my 4 way flashers and interior dome lights. The LEO asked for my license, registration, etc, so along with the automobile documents, I handed over my DL and CCW Permit for FL (Florida's permit is valid in AZ). At this point the LEO asks if I was "armed". I respond with "Yes officer, I have two firearms in concealed holsters." At this point the LEO orders me to reach out of the window with my right hand and open the door. I'm then instructed to keep my hands "where I can see them". I open the door, then follow the next instruction to reach over with my left hand and unbuckle my seat belt. I follow that instruction and then get the next one, "Step out of the vehicle and place your hands on the hood". I do this and LEO begins to go into his "frisking routine", asking "where are your weapons" and if I have any other "weapons" on me, etc. As I'm getting my "pat down", he secures my firearms. After the "pat down", I'm handcuffed and told to sit next to my vehicle. Another LEO comes over to assist, and the two step away to have a conversation. The initial LEO goes off somewhere, and the second LEO comes back, removes the handcuffs, hands me my paperwork, returns my firearms and apologizes for the misunderstanding. I ask him what the problem was, and he basically says the guy is new, and "made a mistake", and tells me that I'm "free to go". I return to my vehicle and re-holster my firearms, then proceed on my way.
Other than the AZ encounter, I have had very little problems with LEO. I've had about a dozen or so encounters in which one case I actually drew my firearm on an aggressor. Only place where I receive "other than professional" encounters with LEO are here in Hawaii (conveniently where we're not allowed to carry). I never carry my firearm here in Hawaii. I follow all of the firearms laws to the best of my ability. I've had 2 problems with LEO involving firearms here in HI. Both times were in the same hunting area. Both instances were with Honolulu Police Officers. The current hunting laws allow you to carry your holstered handgun in the hunting area as long as it's not "concealed" in any way, and is exterior to any clothing, including rain gear. I always comply with the law. On two occasions, I've had officers detain me and threaten to arrest me because I have a handgun in violation of the "places to keep" law. Both times it took almost an hour to clear up. Both cases, the officer secured my handgun and had me sit on the pavement in handcuffs (one day in the hot sun with no shade or water!) In both cases it took my persistence to convince the officer to call his FTO, desk SGT or LT to clear things up. Don't know what the guy was doing in his car on the computer, but in both cases, a simple radio call cleared things up.
Hope some day we'll be able to get some type of "shall issue" law passed here in Hawaii. I like the idea about folks writing to the Governor's office and various tourist groups about wanting to vacation elsewhere. If we can get enough support, then I'm sure we can get something done to fix the messed up laws here. Since many Hawaii residents vacation in NV, maybe we can get some sort of reciprocal law passed with NV??
