Nono, none of them would get you on a list for buying them, they’re basically all common industrial and even household solvents or stuff you’d find in the pool chemical aisle, the issue is you’re effectively suggesting dousing riot police with gasoline as well as things that burn if they get on your skin.

If you did this, they would (rightfully) assume you were trying to SET THEM ON FIRE and you might succeed accidentally given how pyrotechnic riot control can get. This is likely to just get you shot.
