I'm amazed that so many officers depend on the Taser, but blow off pepper spray, supposedly because it doesn't work, In reality, OC does work most of the time for most people. It may not work perfectly and you do have cross contamination and decontamination issues, but it generally is a punch in the face to most bad guys.
OC and Taser instructor here. Taser is like bomb disposal. When it works, it works really well. When it doesn't work, well.....
