The casual and close-range use of pepper spray on nonviolent protesters: It's not just morally bankrupt, it's also not evidence based!
Judy Stone is a doctor, infectious disease specialist, and the author of a book on how to properly conduct clinical research. She's got a guest post on Scientific American blog network looking at the scientific research that's been done to document the effects and safety of pepper spray, and how to treat exposure to pepper spray.
Shorter version: The evidence basis behind the use of pepper spray, especially in the sort of contexts one is actually likely to encounter in the real world, is woefully limited. (It's a lot like tasers that way. In both cases, the research that does exist has mostly been done using physically fit, healthy, adult subjects who are not emotionally or physically distressed in any way at the moment they are hit. They're also being hit using manufacturer recommended dosages and distances of application. Real-world data suggests there's a MASSIVE difference between the effects of that sort of scenario and, say, a terrified teenager being shot in the face at point-blank range. Or an old woman who has been walking quickly, trying to get away from police. Just to throw some hypotheticals out there.) Meanwhile, the evidence that does exist strongly suggests that police forces are currently using pepper spray in ways that are inappropriate and unsafe. Evidence. Not opinion.
