In a similar vein: it's worth noting that pepper spray, mace, and other "nonlethal" chemical weapons are actually relatively lethal[1]. It's hard to estimate exactly how many people die after being pepper sprayed each year, in part because the police exert force to get deaths in custody recategorized into pre-existing medical conditions, drug overdoses, etc.
Yup, wanted to actually add a parentheses talking about this but I'd have ended up on a long tangent. We were also taught to whenever possible provide medical help and we had a big focus on allergies.
