When I was pulling Post Staff Duty Officer at Fort Riley I ran across a drunk carving up a picnic table with a combat knife. When I asked him to stop he started swinging the thing at me. I drew my .45 then backed off about 50 feet and called the MP's on my little radio. I suppose I could have placed him under apprehension and used whatever force was reasonably required to enforce my lawful order...but it was so much more fun watching the MP's beat the guy down with their nightsticks...
