They shot students in the 60's Bastards!
@idlopalev You spelled fuck just fine!
I'm pretty sure those white/clear ones are just extinguishers? In OP.
The ones shooting a brown liquid - that's something awful I'm sure.
@RavenCT No, that's tear gas or pepper spray, tear gas, at least the ones I've encountered in spray form, can be white/clear. It photographs "nicer", that's all!
@phxbillcee Well that's horrible. And why do I expect the world to be any better?
