Come to think of it, from court room psychology, the fillers used make the expert witness more human, approachable, "one of us" and possibly more believable from the trier of fact's perspective.
Just a conjecture.

Hi Simon,
The Um's that you describe are in no way any indication of the level or um failure of a person to possess the knowledge needed for a specific um task.
If I had a $ for every incredible attorney, or GOOD expert witness that used um on a regular basis on the stand, or in conversations. I'd be a billionaire.
Sorry about the um's and comma's
