I can’t find it now, but that particular protestor was interviewed a few minutes later. Apparently the costumes not only provide an effective cushion to stop pepperball ammo without it breaking, but the standard issue CE spray that LEOs are deploying is a chemical gel spray. They sprayed his belt and made the suit smell funny, but did no damage other than clogging the fan that inflates the suit.

Edit; goodnight. I’m off to bed. I’m certain that other lemmings will find the interview that I saw.
