I am not a L.E.O and always enjoy hearing there side of things. It is always nice to hear of L.E.O's that have a good deal of common sense.
When I took my CCL class I asked the instructor if L.E.O's are trained/taught to deal with people that have CCL's, he said yes but all cops are different and often a seasoned cop will likely be more relaxed since he has likely been in the situation before.
My instructor was a retired L.E.O and told us a story of when he was a rookie. He was 23 years old and on one of his first patrols he pulled over a man that was in his 80's. The old man got out of the car and started to approach the officers. The rookie instructor immediatly broke leather and ordered the old man to the ground. (this is what he was taught to do). The senior offficer with him said "man what are you doing? hes 80 years old and his probably just trying to be respectfull" As it turns out that was the case and the old man had never been pulled over and had no idea he was doing something wrong.
He explained that the 80 year old man could of been a threat but a little common sense goes along way.
