Of course you guys are both right... failure of training happens, with some frequency. But the fact of the matter is that it isn't the majority of cases that represent this worst case scenario. Law Enforcement personnel routinely deal with violent offenders on a daily basis with less training than we provide a 4th kyu, in terms of practice time. I can attest to the fact that their training is remedial, at best. Yet, they mostly get away with it. Then, every once in a while, one of them dies.
There is no question that mindset needs to be part of ones training. In Aikido, it seldom is. No disagreement there. We use randori for this. With three attackers who will take you down and sit on you if you give up, folks have to dig fairly deep.
If I have a student who is a professional and very likely to encounter dangerous subjects with some regularity, I send them off to InSights training where they can do some scenarios based training with an armored subject. Greg Hamilton and John Holschen, both world class shooters and retired Special Forces, developed a solid program to augment their firearms training.
If someone is REALLY serious I recommend that they head down to Colorado and do at least one intensive weekend with Peyton Quinn. He wrote
Real Fighting: Adrenaline Stress Conditioning Through Scenario-Based Training
. This book is a must read for anyone who is concerned with application of their martial arts skills. You can check out their website (which is a bit funky) at Rocky Mountain Combat ApplicationsTraining
This kind of training experience can "cement" the skills you have been developing in the dojo. I can't recommend it enough.
I'd submit that police have an advantage over their suspect and us in a few ways.
1) Police almost always outnumber their suspects.
2) Police rarely are in an encounter where backup is not on it's way. Hell I can't even get pulled over by a single police car anymore.
3) Police are actually using their skills "in real life" everyday. If all you did was fight on the street you would probably be a better fighter then 90% of the worlds martial artists.
4) In addition to their police training and constant application of fighting in real life, many police also can choose to get martial arts training. For example, there are many officers in my bjj club who comment often how bjj has improved their ability to control suspects.
