25+ years of practicing law tells me to tell you what I wrote above. You probably haven't been around courthouses and courtrooms enough to know that using your super-duper home-brewed inverted bullet home defense loads is a prescription for litigation disaster (even bigger than putting your client on the stand). However correct your moral arguments about using what you like to protect those near and dear to you are, they are not winning legal arguments.
You may have noticed in your life that what is moral and/or morally justified does not necessarily coincide with what is legal and/or legally justified. This is one of those situations. You can dislike that all you want, but you are highly unlikely to change it.
