I kind of skimmed this, but I figured I have a couple things of interest to y’all on the matter.
First, IANAL nor an officer of the law, nor anything related to either profession… with that due diligence:
Check your state’s gun laws if at all pertinent to what you’re worried about. http://handgunlaw.us/ is a good website for each state and also offers some insight to knife laws as well. Many states are “must inform” states which means that you have to, upon official contact with officers, inform them that you are legally armed. As far as I can make out, from talking to officers, the best way to do this is to cite the legislation foremost and during the course inform that you are armed.
For example, if I were in Michigan and pulled over, I would hand the officer my license and any other necessary materials, as well as my CCW (or whatever your state calls it, mine is a LTCH), and state, “As per MCL 28.425f(3), I am required to inform you that i am currently carrying a legally owned firearm.” Avoid words that’ll set them on guard, such as “gun” or “armed” and, for God’s sake, do not say “gat” or “piece”. Conduct yourself professionally.
Some officers will be fine with that, and some may not be. You are, in most instances, not required to disarm, but most of the time will be “for officer safety.” Just follow officer instruction as completely as possible, and if you are ever requested to handle the weapon(s) in question repeat the command back loudly for verification. There has been at least one instance of a person removing their firearm from holster under instruction from the contacting officer only to get shot by the covering officer, so you want to make sure everyone knows you’re being told to do so. If you do not want to comply with the command to disarm, voice your objection but do not make any movements. You could say, “I do not consent to being disarmed, but I will not resist your attempt to do so.” Again, loudly, but politely. Hopefully the interaction is being recorded, and this could help if later legal action is taken. Hopefully, after being disarmed (or not), the rest of the transaction will go smoothly, and you can go about your business.
For states where you are not required to inform it gets a little trickier. If they ask you if you are armed, your best answer is a non-answer. I wouldn’t be so bold as to say, “No answer,” perhaps, but maybe, “There is nothing illegal on my person or in my vicinity.” The objective is to verify that whatever is in your possession is legal, and therefore any search is unnecessary. Of course, they’ll probably garner from the response that you most likely are armed. If so, just follow the instructions from above (if you like them… don’t if you don’t).
Also of note, you can also request that the officer obtain a warrant to search anything not on your person upon your removal from the car, as it is no longer within your personal reach. Some cops will just go willy-nilly searching you and anything you own, it is your duty to assert your rights as a citizen. If they crap on you, then that’s something you’ll have to consider for legal repercussions later. If you request a warrant or anything and they decide you are being less than submissive, just remember they’re the ones in control of the situation, and your best bet is to be a good witness and lawyer up after everything’s said and done.
All of that being said (I apologize for the long-windedness), my most important advise is just plain not to talk to cops. This is a good viewing, it’s about an hour long or so if I remember correctly, but worth the time if you’re worried about interactions with officers. - YouTube
Bear in mind, all of this advice applies to dealing with officers in official capacity, if they’re your drinking buds, and they know you personally… then assume whatever your personal relationship is with them. Maybe just ask them questions and figure out the nuances of their particular department, so that you could be better prepared for any official interactions with their colleagues.
