We are on a debate that can go on forever. BUT have any of you ever been face to face with someone high on drugs that is angry and pumped up on adrenalin? That mace, wasp spray or whatever type spray you use, sounds very good, BUT if you are close enough to a drugged up assailant that you can spray him you are in trouble. A drugged up, angry, pumped up on adrenalin person will hurt you or kill you.
They are stronger, more resistant to sprays than anyone you have ever come face to face with. They will stop for a moment and come at you again. Sometime around a campfire, ask me how I know this.
Bottom line a person like that you better be able to stop them while they are 30 feet from you, not close enough to touch them.
Think carefully about your choices of protection, once you make that decision, don't discuss it, just have it there for your safety.
Soap box is now being put away.
Love you all and want you safe.
