People are all over this on twitter, I'm sure law enforcement will be following this assault.
It appears that antifa planned to use cement as a milkshake replacement. Whether they intended to cause chemical and exothermic burns on their victims, or just cover them in goo is tbd.
There have been threats by antifa to attack with muriatic acid, and blind MAGA supporters.
The assault on Andy Ngo will hopefully help leftists realize they have been on the side violent of fascists the whole time.
