My area of expertise is more in in the realm of physical fights, fistfights.
And at 85 years of age, I have been around a while.
I had a part-time job as a bouncer, in Liverpool England, a rough sea-port.
1960 till 1965. The first 4 years at the Cavern Club of Beatles fame, on a very narrow Street, Mathew Street, a lot of fights at the Cavern. I was stabbed twice at the Cavern. My final year, at the Blue Angel, an actual night Club, on Seal Street. In 1965 my Family and I moved to Australia and stayed for 3 years.
My first Wife hated Australia, and we sailed off to Canada, promptly were Divorced. But went back to England, for a week, my Mothers funeral.
The fight I was involved in, during a night out at an Indian Restaurant, The Moon Glow. Involved 4 young thugs, around 18 years of age. Who in my estimation were attempting to leave without paying, in local speech "Doing a runner" using our group to make it easier. My wife and I my brother in Law
(useless) his wife, my wife's younger sister. We were 4 also, but only two men.
How does this fit into a gunfight? I decided to start fighting, as a solution to being attacked. My years of fighting made picking targets, damaging all four in a way was almost a clinical exercise. According to the report of the Police, I called, to the scene, caused two broken noses, one broken arm (a chair!) 4 broken ribs, a front kick, heel landing first. Information from a radio call to the Cottage Hospital Emergency ward, made by one of the Constables.
Moving forward to now my Glock 19, concealed, a single armed individual, or two. Already pointed handguns at people, not fired, not panicked! Once in Detroit, once in Rochester. Both times on my own, in my vehicle.
I remember distinctly seeing the sights.
