Yeah, this is ridiculous.. you need some training. I taught self defense techniques for years. You know what MOST killers with a gun do, when you blind them and put them in pain? They start SHOOTING RANDOMLY.
Wasp spray (or pepper spray...the assertion that Wasp spray is better than pepper spray is ridiculous. There are high concentration pepper sprays that can hit a target from 20 yards....more, with the pistol variety. Try using wasp spray on a bear, and tell me how effective it is...) is great against a guy with a knife, or against an animal; someone or something you can run from; because they cannot see you to catch you. It is SUICIDAL against a person with a pistol. You cannot outrun a bullet.
And how are you going to feel about the church members you kill or maim in attempting to shoot the gunman?
You are a "In my weapons I trust" man, all the way.
