Well, I was in a street crimes unit for 25 years, and the more resources in ones arsenal, the better chances for a successful outcome. One can never anticipate and must be equipped and ready for ever changing and new encounters.
Which makes this attractive. Plus the fact that I saw a PR about a demo for NJ league of Municipalities. A state that is gun shy on lawsuits and a lawyer for ever cause.
Thats why I think an alternative resourse like this might fly with a good sales team and marketing effort to LE communities who are shy of using the current popular choice and to those using it as another method to disable.
