Having read through all of the posts, my take-aways are:
Avoid interaction with LE at every opportunity ( everything you say and all). Don’t speed, come to a full stop, do PMCS regularly on your vehicle etc, that IS under your control.
Avoid involving oneself with situations that do not directly involve yourself or your loved ones, be a good witness, use your cell phone camera long before your sidearm maybe?
If unable to avoid either the above, insure that your weapon(s) are holstered or otherwise secured long before the LEOs arrive, declare yourself “ a good guy”, and most importantly, maintain situational awareness (head on a swivel, focus on the whole of the immediate area and assess what you see/hear/sense quickly; decide based on that input. Remember, another CCW type may not know that you are a good guy either!
Regarding CCW and LE interaction- know what is required by law- do it. Never assume that any cop is either a good or bad guy ( just like any other person you encounter and interact with n the street) but, have a plan either way.
If being armed is an occasional thing, then I think you are more likely to have issues than if it is an everyday all the time mentality. If you are a “newbie” at this lifestyle, then I suggest participating in role playing and competitive marksmanship ( IDPA or USPSA etc) to burn off the butterflies and nerves etc. Never stop thinking….
God Bless the good guys, whomever they are.
