The term “caveat emptor” has never been more aptly applied than to the self defense industry – where fly-by-night outfits and instructors try to convince the unknowing public that they have the solution to all their safety needs.
The problem is…very few of these people have the background or knowledge to really diagnose danger (and how to effectively deal with it). So, when you are seeking out self defense instruction, the rule is caveat emptor.
