You are so wrong it’s difficult for me to not get rude with you. Either you are stupid or are just trying to put forth an idiotic leftwing mentality. Tear gas is a largely inert gas. It makes your nose and eyes run. A lot. It burns quite a bit. But it’s no more illegal than pepper spray. Tear gas has NEVER been banned by the Geneva Convention. Mustard gas has. But stuff like VX which will kill you in a short time and make you were dead even faster isn’t banned. Biological and germ warfare are what is banned. But you just give it a few more years and the lefts buddies in the Middle East like ISIS or ISIL or whatever there name is today will be using it. We have been most fortunate over the years since 9-11. I hope we remain that way, I doubt we will. I’m a US Navy veteran. Combat veteran, 12+ years active duty.
