As a full-time LEO, here's what strikes me about this incident: Proof positive that the armed citizen can, and will, save LE lives. This type of thing has happened before, and will happen again. My uniform is not a Superman costume....in other words: Sometimes, the protectors need protecting. To all of those left-leaning, brass-wearing desk jockeys that Sarah Brady loves to quote as saying that "civilians" shouldn't own guns, here's a poke in the eye for you. Great story!
