Aside from the obvious, “Why the H*LL were those disrupters allowed in and continue?”
Why would the producer (or person in charge) cut to the protesters? C’mon! If it's about image (and it is) why let it on and give then their fame?
I fear that the producer was lacking or a Dem as well. It's just not what you do. Recall the IRATE producer at the 2000 Dem Convention “I WAN'T MORE F’n BALLONS!” That's what it's about.
