Excellent article, thanks for posting.
I wanted to do a serious post, but most of them are so silly that at this point in the thread I don't imagine mine will be read by many.
The best point made in the article was made by the WWI vet. Anyone who has taken martial arts by an instructor with a real interest in self-defense will tell you to put out the attacker's eye or break his windpipe. Of course for a cop, those are "save your life" tactics that he shouldn't ever have to use, but as in the story, he might need them.
IMO, it was very obvious that the officer's training was flawed. If you pepper spray someone with no effect, don't waste your time with a baton. The reason that professional pepper spray has a 12 foot stream is to disable someone before they get close to you. Why would you want to get close enough to an attacker who laughed at your pepper spray to poke him with a stick? PULL YOUR DAMN SIDEARM!!! Unless you were planning to put out his eye or break his windpipe with the baton.
I won't bother with the stopping power debate. There have been people stopped by a .22. There have been people not stopped by a .45. I watched a deer run nearly 200 yards after a 30.06 round had made jelly out of his heart.
