Security guard I know was trained in using pepper spray and also found it miserable. They were required to experience it by the instructor. However, it seems the chemical in it causes more misery to lighter skinned people for some reason. Darker skinned people are less effected. And of course black people are least effected. As it was described to me there is quite a difference in how debilatating it is when used on caucasian versus african people. All this apparently was known by the instructor.
Any instructors or others experienced in pepper spray able to confirm or refute this?
