Question is though would people feel so emboldened to go do that and commit all of the damage and theft like that if their identities weren't concealed and they could be filmed? Would Antifa go march around dressed like that if it was socially encouraged that people had facemark on? I think it would make them an easy target to distinguish as criminals and the deniability is greatly reduced.
