RUSH: “Public Broadcaster Admits to Increasing Booing Sounds During Trump Davos Speech — German public broadcaster ARD has been blasted after admitting it ‘boosted’ the sound of booing” at Trump’s speech, and they had to boost it otherwise nobody would have heard it because there wasn’t very much. 

That’s why they were caught. There wasn’t anything in there really to boo, other than if you didn’t like Trump personally.
