This is an example of one of more than one-hundred videos in the D.A.M.E course taught by Harry L. Sher for locksmiths, government agents, risk managers and security experts. D.A.M.E. is the acronym for Defenses Against Methods of Entry. It is a course that Harry has been teaching for more than twenty years, produced by Marc Weber Tobias. Originally the series was published on disk, and is now online.
