That is called street smarts. It will not show as my smile will blind you to it but I'm watching every move you make, especially your eyes, they will telegraph your intentions, and where your hands are. As for the last statement about interfacing with criminals that depends on where you work. Barney Fife wouldn't know a criminal from a peony. In the major metromesses you deal with it every day. In a normal month I would hazard a guess I saw more than an officer from a under 200 person force would see in 2-5 years. It didn't help any that I spent 75% of my time in a minority section of town. Made a lot of friends and thoroughly enjoyed it. Treated people as I would want to be treated. Worked 75% of the time anyway. Would I do it today, NOPE, NO, Hell NO. Totally different attitude on both sides of the street.
Trust me, I get street smarts after 7 combat deployments to IRQ and AFG. Heightened situational awareness is one thing, but assuming everyone is a threat until proven otherwise is horseshît. Sure, on the inside have a plan to kill everyone you see, but that can’t bleed to the outside.
Maybe it’s confidence bred thru experience, I don’t know.
