Re: Bad Advice and Self Defense
The unspoken "crime" with these people who readily take money while leaving a person with a false sense of security has to do with the "Learning Curve." This woman, having spent three classes working on a certain skill set, should be able to replicate that skill set for a BRIEF period of time after the learning. The ability to replicate this skill set quickly declines until it reaches a baseline that is somewhat above the previous baseline.
The moral of the story is unless you actively practice your skill sets under conditions in which they are likely to occur, then the likelihood of you being able to fully utilize that skill set is not that good. There are few situations more dangerous that people with a little knowledge and skills assuming and acting as though they have a lot of knowledge and skills.
