Sorry, you again state (make it unlawful to carry for such purposes), which suggests the carrying of wasp spray or any insecticide as a self defense weapon.
I was only speaking to the use of any wasp spray or insecticide as an emergency defensive weapon, if someone attacks you and that is all you have at the time. Such as you are in your yard, someone attacks you, and you have the spray in your hand because you were dealing with a wasp nest. It is the defensive weapon you have, to try to delay the attacker to gain a secure position, get in your house, be able to draw your firearm, but it was NEVER stated as something to carry with you as a self defense weapon.
I do not know of any law that would hold you prosecutable for using an insecticide that is not by the federal approved method when you are defending yourself.
That is why I asked about the carrying and who suggested it. As it seems you are addressing an issue that was not brought up that I can see. Did I miss someone suggesting the carrying of insecticide as a defensive weapon?
