On a domestic disturbance recently... After calming the situation and detaining the aggressor, I looked up to see the complainant coming toward me and a fellow officer at a fast pace. I asked her a question and when I did she showed her hand from behind her back and was holding a razor knife. Luckily, she dropped the knife when I drew and ordered to drop the knife. She was within ten feet of me by that time.
Needless to say it was an eye opener. Never let your guard down!
