I love the way some “instructors” put together a resume. They can sure make things sound impressive to the uninformed. Now any idea should be able to stand on its own, so this is not about the validity of a technique, it is about somone using credentials to try and sound impressive. Using Google you can take a posted resume apart and see what the claims actualy tell us.
One thing to look out for is the claim of being “certified” in a technique. For example “Some impressive sounding school: Certifed tactical leader”. All that may mean is the person attended a 8 hour class and passed a multiple-guess test. A big difference from something like “Florida Department of Law Enforcment: High Liability Instructor, Handgun Instructor, Rifle Instructor, Shotgun Instructor”. Being a certified instructor is a lot difference in being certified to perform the technique.
