A mannequin made of rubber should move much like a dead human. But be careful or the head might flop too much and tear the rubber. This explains the careless handling by the guys dressed as medics. Make sure the rubber head does not flop unnaturally or tear off.
As for the legs. Even though they normally make legless mannequins, it is not too hard to dress up a mannequin torso with some legs. You would have a floppy mannequin so you would need 4 people to lift it/roll it onto a stretcher so that the floppiness was not so noticeable. And they did use 4 guys.
There may not be conclusive evidence one way or the other, but this is a very suspicious event and there are things that do appear like use of a mannequin.
Another suspicious thing is Floyd's work record. Nobody seems to have confirmed where he was at what dates. If he was in prison for 5 years, and mostly was in Houston, what were the dates when he worked at the same club as Chauvin?
There has been talk that both worked there for some 17 years, but that does not fit Floyd's bio unless the twin was using his brother's identity. Which leads to all kinds of additional questions.
