TL;DR they're just regular smoke grenades.

It's mostly for "we are evil" branding. Mix well with purple.

Whatever it is, every ice agent should be forced into a room filled with it.

tldr

We don't know what gas grenade it is or what's in it. But there is old data from grenades that look similar, and those old grenades are safer than normal tear gas grenades.

But we don't actually know what they are. They could be anything.

Whatever this is, tear gas, cs gas, is not harmless as is often thought. It causes permanent damage, and is actually a nerve agent, different than what we call nerve agents, but it hits pain receptors in nerves.

Likewise pepper spray would not cause permanent damage but I heard it is often mixed with pfas and other poisonous shit but idk on that source, the tear gas bit was in propublica in 2020 during the blm protests.

It's just a regular ol' smoke grenade like the military uses for signaling. At least so say some people on the ground in Minneapolis who recovered one of the canisters.

“The green dyed smoke suggests high toxicity to protesters,” he adds, “but the effect is more psychological.”

This isn't saying that it's not toxic or dangerous, it's just pointing out that once again they are adding in a layer of purely psychological terrorism, which should be of no surprise to anyone who knows how much these pathetic evil fuckers rely on kayfabe. The green dye is added for a dramatic flair.

They're dangerous, and you can't underestimate them, but don't forget they're hoping to put you in trauma by being as fucking overblown and dramatic as possible. Consider it a deliberate cutesy attempt to add insult to injury for the benefit of their own ego.

If you know how mentally ill narcissists operate, you should understand the thrill they get from constantly terrifying a captive audience.

They're not even the first dramatic little bitches to use green gas. They just ripped off the fucking Joker and Smylex because nothing they do is ever original.

The Minnesota tribune article calls out the manufacturer directly: https://www.startribune.com/border-patrol-greg-bovino-smoke-canister-chemical-spray-ice-protests-observers-minneapolis-dhs/601568184

Luhmann took video of one of the empty smoke canisters, which is labeled as “pocket tactical green smoke,” made by the company Defense Technology. The back states that it should be used only by “trained law enforcement, correctional or military personnel.”

Below that, it states that anyone using the canister “should be trained in deployment, decontamination and first aid procedures.”

Defense Technology (and their shareholders) should be having their names spread far and wide for selling weapons to terrorists murdering American men and women. Hit them and all their enablers in their fucking pockets.

Here is the company's contact information including phone number, fax, and address for domestic sales in Casper Wyoming. They should open bright and early Monday morning so give them a jangle at (307) 235-2136 and let them know if you're satisfied with their products.

It's proprietary Soylent Green flavoring.

They are seasoning.

If you can see it, it's easier to blow back with a leaf blower.

It really should be said that this expert is talking out of his ass here. He hasn't positively identified the specific gas being used, just a similar product by the same manufacturer, and he definitely hasn't actually measured nor tested the gas at the scene. It's an educated guess, but still a guess.
