This list must have been made up by “The Onion” because it is so stupid as to be hilarious. Won’t go into details by my father worked on gas masks and WP mortars during WW2. Today’s chemical weapons are far superior in effect, even non-lethal ones so that the Antifa trash would collapse in their own puke and crap if they were used against them.
As for their alley tactics. Our men learned how to fight in Mogadishu and Fallujah. Would wipe out Antifa in seconds.
Seriously, who wrote this garbage, a leftist college graduate?
Yes, many of those people are "leftist college graduates." The point here being, even if it would probably turn out more dangerous to them, than to others due to their lack of experience, their basic premise is correct.
Example using granular chlorine (for pools) and muriatic acid (for pools):
Ca(ClO)2 + 4 HCl → CaCl2 + 2 Cl2 + 2 H2O.
Chlorine gas, Cl2, is a resulting product (along with Calcium Chloride and water). Very dangerous, if "used" improperly and definitely something that we don't want seen "deployed" in a major America city...even if it is the liberal hell-hole known as Seattle. Those morons could hurt a whole heck of a lot of innocent people.
