Antifa covert weapons tactics and quick-set cement Several months ago I spoke with two 3%ers who had attended a demonstration in Portland.  They said that they had found a bunch of weapons stashed in the bushes and brought them to the attention of the police.  The police thanked them and confiscated the weapons which included sticks with nails stuck through them etc..  The police were confiscating any weapons they saw and Antifa were trying to overcome that by hiding weapons in the demonstration area. A large milkshake cup filled with hardened cement would make a good covert weapon.  Perhaps those that were hit and spattered with wet quick-set cement were attacked before the cement had finished setting.
