@jon357, I have seen both the moment when Putin's speech was cut off - the TV broadcast and the video made by one of the people in the audience. There was no booing, he didn't stumble and, to be honest, I didn't see any reason for his speech to be cut off on purpose. They claimed it was a technical glitch, as far as I remember, and maybe for once they told the truth lol
There are all sorts of suggestions, including using a green screen and using a double.
I've even read in a Polish article that it could be Putin's hologram! lol Sorry, but that's just ridiculous, imho.
Yes, I've read that people were bused in, that some left after they had their tickets punched, some others left after Putin's speech (and I've seen videos of them leaving) and I find it believable that some of the audience footage could be from some previous rally at which people were showing more enthusiasm. I'm yet to see any evidence though that:
- Putin wasn't there,
- his speech was cut off on purpose because of something embarrassing.
Without evidence it's just our wishful thinking...
