The video looks to me like he was injured. They had to carry him to the van. Now, he could have been faking it, I suppose.
Alright.
If that is the case, and he was injured after arrest and prior to being placed in the van, I would think that a beating that resulted in his injuries would have been seen by someone in a city setting.
That is just an assumption of mine, but it seems like it would take a pretty severe beating to cause that.
Secondly, had he received those injuries prior to being placed in the van, then I am curious what the prisoner inside the van heard in terms of him saying that he thought Freddy was trying to injure himself in there.
It seems unlikely that a person with his injuries could move to any great extent, or even request medical help with a crushed voice box.
