So her having nothing will be better, ok.no thanks but you do you
It's not necessarily that her having nothing would be better but her having nothing wouldn't be any less effective than having something that doesn't work.
Like almost everything else I post I've said this before, several times.
I worked as a security guard for 15 years.
I had multiple encounters with homeless people and vagrants while I was working. As a security guard I was required to wear an approved uniform that very clearly identified me as a security guard. I was almost always wearing visible body armor I was almost always carrying a visible firearm.
Almost across the board every single time I approached somebody to remove them from property the first (Printable) words out of their mouth were "What are you going to do shoot me?"
A few of them drew weapons on me
knowing that I was armed with a handgun.
But almost without fail every time I took the fox Labs off my belt and started shaking it up I got
instant compliance.
I really believe that most people don't actually think you're going to shoot them but they have no such reassurance that you won't spray them.
I said all that to say that your daughter would probably be better off with a great big can of whatever OC your local police department carries than with a pepper ball gun.
I say this with one caveat. I don't like gel sprays. Gel sprays, in my opinion, take too long to take effect
I have respiratory issues and even with me gel spray takes too long to take effect.
