Nobody said he got the injury by rolling around. The medical examiner said the injury was consistent with a bolt on the back of the van. Why is Carson commenting on the injuries when he hasn’t seen the autopsy?
He's just another poser!
Why does he feel compelled to comment at all?
Yes. Just that statement suggests that, at some point, he was slammed into the bolt. I don’t know if this could have been self-inflicted or not, but the defense will need to find a doctor that believes it could have been self-inflicted. It is never a good idea to make any comments on a hot button situation until all of the FACTS are in. I doubt Dr Carson will make the cut for President, but he would make a good Surgeon General.
