Being a LEO.... I have stopped many people that were armed and told me so.
I have found a few that hada CC permit on file and I asked them if they were armed finding out they were.
For me.. I assume EVERYONE in the car is armed.Any LEO that does not or is counting on you to tell him is a fool.
I would suggest you tell the LEO since there is nothing worse them him seeing it and drawing down on you thinking you were hiding it for some reason. Remember... he does not know you or what you might have just done. Plus it is just a courtesy thing.
But the best thing you can do when stopped is the following and this will allow both of you to go on your way safely.
At night.... turn on your dome light!!!
Keep your hands on the wheel!!
Do not move all around!!!
Roll your window downunless it is already rolled down. Have rear seat passengers roll theirs up!! LEO does not like passengers having easy access to the gun belt.
Wait for the LEO to ask you for your license and registration. He may not even want it if he is just telling you about a low tire.
The officer should greet you and advise why you were stopped.
When your turn to speak comes.. advise that you are armed and the firearm is (insert favorite place to store your gun) and you have a CC permit (If you have one). You may want to ask what you did wrong if you were not told.
If you need to find documents in the car let the officer know where you are going to search to get them. Reaching into obscured places make a LEO nervous. He has not ran your name yet so he has no idea if you are a wanted criminal or escaped convict.
Put your hands back on the wheel while the officer is there.
Stay in the car!! If you want to get the officer's attention.. hold your arm out the window.
When the officer returns to your windowbe sure to put your hands back on the wheel.
Now is not the time to argue your point about the violation. Go to court and let the Judge know. The street is not the place to debate the violation.
Remember.... so fewmotorists are nice during a stop that those who are polite have a greater chance of getting a warning or reduced charge.
