maybe, maybe not, the other night when Sarah Silverman was being booed very loudly, she was angry at being on the receiving end. Hot mic revealed "...well, they can take care of in post...", meaning post production of video - careful video edit, sound edits.

If you watched the Trump rallies you know that they focused tightly on Trump solely, no crowd overhead shots or pans. Trump called them on this repeated during every rally and boldly challenged them to pan and pullout shots. And the crowds respondly loudly.
Contrast this with the Trump rally.
One or two people would yell — EVERY camera would pan over. The one protestor would be the only story from the event — where 30,000 people were turning up.
Here, dozens, over a hundred, up to 1800 according to one story delegates to a convention walk out in the middle of it led by their candidate and... crickets.
