They might know "some" things, but it is not their area of expertise. They are no more qualified to comment on it than anyone else who takes the time to look into or study it, and you do not have to be a doctor to do this. But the extent of this doctor's knowledge is that he "can't help but think" helmets are reducing the severity of the injuries he sees. This is not evidence that helmet laws are useful, it is idle speculation.
