It's available where I live.
I have heard no reports of it falling into the wrong hands or being used against women.
If that argument were valid, all women could feasibly use for defense is our own hands and feet, not keys, not handbags, not stiletto shoes.
The fact that women might fight back, even to the point of pulling a gun on an assailant (that's legal here too) doesn't stop men trying.
The problem isn't that women need more means of defending ourselves.
The problem is what goes on between the ears of men.
What are we teaching boys and men about women and girls, and about themselves?
What are men and boys telling each other about women and girls, and about themselves?
The problem of men attacking women won't stop until men decide to stop it.
So far, all they have shown themselves capable of on this matter is willful blindness and complete disregard.
