Smooth move, Ex-lax.... But the debate is not about Arnold Rowland.... It's a rebuttal of the insane proposal that it's possible for a person on the 6th floor of the TSBD to hear and understand a police radio message from a radio that was a half block away.
How exactly is it insane? The motorcycle wasn't even parked where Rowland was standing. It wasn't the only police motorcycle there. We know from Rowland's testimony that the radio could be heard by bystanders in the area. Do you know how loud the radio broadcast was? Presumably pretty high to be heard over a motorcycle engine. Again, though, this whole issue is one of little relevance since Oswald required no real time progress report of the motorcade. He knew the approximate time for media reports. Most such events run behind schedule. And the crowd and motorcade noise could be heard as the motorcade advanced. Giving anyone in DP advanced notice of its approach.
