"white noise" devices intended to mute the Bernie protestors, then also the fake Applause devices for speeches. Also people "paid" to come and fill seats, taken from Bernie supporters.
Crooked Hillary.

Another view of white noise machines, people paid $50 a day to wear Hillary shirts and sit in the seats reserved for them.

good one. see at 4 minutes where one reveals the plan and how when called on it they hid their credentials and left. The paid people with Hillary shirts were supposed to stand every time they Bernie supporters did and try to overshout them, all while the white noise machines were used to try and silence Bernie supporters too.
This is absolutely scandalous and shows just how Hillary wants to govern as President, if she's elected. She will try and cut off everyone who disagrees with her, use every gestapo tactic she can.

a delegate describes how his and other's seats were filled by people who were paid to sit in the seats.
after Bernie supporters all walk out..... So much of the applause and cheering heard has been paid for at $50 a pop. LOL
