This is an old FBI training video showing classic defensive shooting techniques of days gone by. While it is entertaining, there are some demonstrations of how bullets don’t necessarily bounce off a surface at the same angle of intercept as a might a rubber ball. Rather they ricochet and skip along a surface to reach a target hidden behind a cover and concealment. You can get a good idea of how this knowledge can benefit you as a shooter, or get you killed if you think you are safe behind cover and concealment.
