Once in my youth I had a police officer jump out of his patrol car as it screeched to a stop about 10 yards in front me and shout, "freeze" while pointing his shotgun at me. His partner, the driver, added a very large caliber revolver (looked to be in the 30 mm range
) to the fun a second or two later. These were trained police officers, but both were very excited and a little frightened. Once they determined I was not the bad guy, and just a stupid kid in the wrong spot at the wrong time, all was forgiven. That was about 40 years ago and it still makes my blood run a little cold. To say which weapon was more intimidating would be difficult.
