“Stage rushers need to be NUDE:”
How ‘bout a bunch of nude persons jump onstage and prevent the “Trump” from being assassinated.
I’d pay to see that!
I still say noises that overcome anything going on on the stage. A crowd of people with cop whistles would ruin the performance and drive the audience away. It would be pretty easy to keep from getting caught. hang the whistles on a lanyard and hide them under shirts, etc. Disturbing the peace would be the most they could pin on the whistle blowers.
