These days the authorities are actively getting ready for the upcoming opposition public meetings. Several days ago a lot of people witnessed two water-spraying cars and one car full of barbed wires going to the center of Yerevan. Of course they will keep these facilities till November 27 in a safe place and then they will use them if necessary. By the way, recently police officers are working too: they call active oppositionists to police departments and talk to them. This is done mostly in Marzes where most active people are taken to police departments after oppositional meetings.
