But folks, that what experts witness testimony does and why it is so useless. All of the stories the defense is telling are plausible stories. They get to say anything they want to and they are not required to prove it in any way. They never have to be right, they only have to confuse you. They can accuse the Alberts, they can harass witness through surrogates, they can drag every police officer through the mud, they can berate the poor paramedics. They get to do all of that without any proof what-so-ever.
The expert testimony is summarized as: "We can't figure out how this happened so it probably didn't". We know because me and my friends myth-bustered a car hitting him..."
Its was almost idiotic what they said on the stand.
