I have absolutely no desire to kill anyone in self-defense if at all possible and would much rather temporarily debilitate, as circumstance and training allow, and openly carry such a device in cross-draw when in public in Maryland.
For reference to those who are unaware, OC spray is only viable to ~12ft. An OC launcher is viable to ~40ft.
I'm aware of Teuller (21ft) and would of course draw a firearm at that close range if threatened with lethal force of grievous bodily injury.
