The Rules of Gunfighting
Some of these remind me of the old Kenpo thing that it's better to be adjudicated by 12 than carried by 6. But what's a little macho posturing between friends? And can you beat the pithy wisdom of "Anything worth shooting is worth shooting twice."?
Of course, the odds are pretty good that none of us will ever need these rules, and if I do ever find myself in a gunfight, I'll be the guy cowering under a table.
