Bill, for most of the unschooled population you're undoubtedly right.
But I think we should also "get past the metal" in thinking about this debate. For example, I was just an average student on my fencing team. But it taught me what to look for, and how to reposte and remise. Now imagine a guy with some real training.
One of my truly different clients was a Marine who served one and only one rotation in the middle-east. With all of the manpower shortages, he applied and they didn't want him back.
There's a C/W song that uses the phrase "all shook up like a quarter in a can." and that aptly defines him. He cannot sit still, and if he is forced to stand quietly while I finish a knife, he twirls another one and rolls it between his fingers like a Vegas magician does with a coin. And these are my knives.
In all honesty, I doubt if he would even feel the first few shots as he attacked you. And even if he died at some future date, his own blend of tenacity, speed, Escrima and anger would hold him together until his target was long dead.
He is definitely one of a thousand.
But here's the thing which we should remind folks. He looks like an average guy with a high-n-tight haircut. He's of average build, he wears civilian clothes, in fact, pleated dress pants if he's coming from work. Until the first ten minutes go by and he's off onto one of his many bizarre conspiracy theories, he appears like the kind of guy you'd like your sister to meet.
People, weapons, theories, education, knives and their alloys, condition of their maintenance and the tenacity of the user all vary. What might scare me angers the next guy. And I'll wager that many of our forum members here have met at least one of these wild guys akin to my client.
