But we may not ever hear about the failure of this form of self-defense. I'm willing to wager that a good chunk of those rapes are due to the null efficiency of these kinds of weapons. To the credit of those who manufacture such devices, not all of them are going to be as ineffective as my friend's. But I happen to trust Murphy's Law in this case. Some of the watered-down stuff gets sent to a place where stronger stuff is allowed.
Someone brings the weak stuff from a place they just moved from.
You get the idea. These devices have also been shown to have a lessened effect on people who are under the influence. Worse, what about women who would like to have such protection but cannot, due to restrictions, such as being required to register, have a license, or take an expensive course. This is a total outrage. There is a way around all of this bureaucratic nonsense.
