Btw isn't it just absurd, that tear gases as 2-Chlorobenzalmalononitrile (or as I use to call them: poison gas(es), while not being nearly as nasty and toxic as say Sarine or Novichok agents, show still significant toxicity and are dangerous), are prohibited weapons to use in wars, which already are situations in which human morals are mostly thrown into the bin, covered by the UN, while it seems to be totally cool to use a weapon that is considered insidious and illegal of which only dictators and the like make use of.
Big surprise: your government is no better than the bad, bad countries you're told about..
