I work in law enforcement as well as instruct CCW part time. "Greywolfservices.com" I have to keep up with the laws. It's good that you carry the ord's with you because not all officer's are aware of them. There are a lot of law's to keep up with and they change every August.
Depending on the situation and how your information is presented to the officer will in fact determine the duration of your time together. Don't be the guy to that throws the paper at the officer saying, "Look- I told you so". Just use common since. He has a job to do. Don't make it more difficult for him (and you).
I am not saying that you act in this manner, I am throwing this out for everyone who is reading this.
Another comment on open carry:
It's nice to have this option, but, use that gray matter between your ears. If you decide to walk down the streets of downtown St. Louis with your weapon on your side in plain view- Don't do it alone. As always, there is safety in numbers. It will appear to the courts that you were looking for a fight. (Vigilante style).
If you have to remove your weapon from its holster to resolve an issue, whether you fired it or not, call the police and explain what had happened. If the other party leaves, get a good description of them, direction of travel or vehicle and license number.
If you don't call, they will. They will make you out as being the bad guy with the gun. We deal with this a lot. It does happen.
Have to run for now. I will throw in another 2 cents when I get a chance. Remember, Practice - Practice - Practice!
