Most likely carrying a striker fired pistol without a round chambered. If that's correct, we'll never understand why a state trooper on hwy patrol would ever not have his weapon loaded and ready. IF it had been, we would hopefully be reading a different version of this story and hopefully not be paying this scums life in prison privileges from here on. There is a great lesson to be learned here for us all, check your equipment often. Prayers for the trooper and his family.
