"The kindly Leo's of my city recommended it, and I trust their judgment." 1st defense, 2nd, I feared for my life, every defense.
As a history lesson, when I was about 7 yrs old, the next door bully and me tangled, he was older but still very young, maybe 8 or 9, outweighed me by 25 pounds, long story short, we tussled and he wound up sitting on my chest and punching me, no big deal as my POS paternal father regularly hit me with his fists, I was really hard to hurt, UNTIL, he hit me with a bicycle air pump in my teeth, that P*ssed me off, laying on my back in the entrance to the garage at my aunt's house I reached for what was there, a can of Raid, now that was 44 yrs ago, there was only 1 Raid, and I sprayed him in the face, at that time it was probably chlordane in the can, it achieved an immediate response, he could not breathe and looked extremely worried, he got off of me and ran next door to his house, followed by a trip to the emergency room, while he was gone, I started making weapons, out of rolled up newspaper and spent safety razor blades, fearing his retaliation, funny thing, he never even came close to bothering me again. 1 of the qualifiers of many that put me on the path of don't be a victim. I don't know if he learned his lesson, or his parents used it as a teachable moment.
Kinda feel sorry for him now, but I was defending myself on my aunt's property, and had not bothered him.
I think the point that might be missed by some is, you used what was available! You didn't place the can their with the intention of using it against another person. If someone today takes a can a wasp spray and carries it around the house with them or stations several cans around the house in strategic places for defense, well I just think their going to have a hard time defending that in court. Be it in criminal or civil court. I think you would have a better chance of using good pepper spray or a firearm!
And I think I would ask those kindly LEO's if they're also willing to take the stand in your defense if you ever do end up in court for using wasp spray! Your word that they recommended it probably won't pass muster.
