Having a license to carry doesn't mean you can reach for the weapon, or anything else, after informing the officer that you are carrying, without his command to do so, so that tidbit means nothing in my opinion. The officer didn't pull over the vehicle for a broken tail light, but rather because the victim was a possible match for an armed robbery suspect a couple of days prior. As for not having prior convictions...the victim had 22 arrests on his record, and while none were for violent offenses, the officer can't assume this won't be the first time. Like you, I am non-committal on this...I'll wait to hear what the investigation determines, but I suspect that whatever the outcome, it won't satisfy those whose main purpose is to create a more contentious environment for both civilians and police alike.
