Had over three decades "on the job"....I always assumed everybody I came into contact with was armed. If a citizen informed me they were during a stop or whatever, I thanked them. I am not a big fan of having people hand over the carry gun for me to run the numbers. You extended me a courtesy, and f law breakers don't do that. So to me it is rather pointless to run the numbers, plus it involves a lot of gun swapping back and forth from akward positions, and I am not fond of that.
And as a TO ( trng officer) I didn't encourage rookies to take loaded guns from citizens.Because most of the time the officer was totally unfamiliar with the loaded weapon. Most cops are not "bullet heads", they carry a sidearm because it is a condition of their employment. So to assume that an officer is a weapon expert is not recommended. I was a L E firearms instructor for 25 years and know of what I speak.
You as an armed citizen need to know the laws and reg's in your jurisdiction. Most of us "on the job" know that we cannot respond fast enough to save your life or your families if there is imminent threat. And we want every law abiding citizen to be able to be safe. Get some competent trng, enhance your skills sets, and have a defensive mindset. Be safe.
