Antifa bombing... the next phase

If you look closely at the Boston marathon bombing it was done by a couple of guys with a book bag that was supposedly form Russia. They dropped their book bags off in a crowd and left . What I have been witnessing with these Antifa protesters is they are all dressed in black carrying black book bags. It is illegal to cover your face in a protest from what i understand I do not know if its true but the FBI would have a very very hard time tracking this person down even with all these cct cameras everywhere.
Im sure with all the infiltration Antifa has done in the media they will have no problem passing it off as a white supremacist.
