The law doesn't say anything about "official contact". The law doesn't say anything about "official capacity as a LEO", and it doesn't say anything about "investigating a call", "asking for witness info", and it sure doesn't say "and so on".
What is says, is "during the course of any arrest, detainment, or routine traffic stop." That is all it says, and that is all that the law requires.
Why do people keep trying to read more into the law than what is there?
You try spitting hairs with the police and see just how far that gets you.... Geesh, guys like you need to use a little common sense when reading these posts and not get into a hissy over every little thing someone posts and calling people out... the law is written with a lot of ambiguity in it so as to leave the police a wide range of authority.... depending on a wide range of situations.. it doesn't have to spell out every single specific situation that the law would apply too. You pulled this silly crap over on your FB page 'I Support Open Carry in Oklahoma' and I left it because it was your page.. but don't start silly nonsense over here on the OSA forum.
