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.
Amazing. If Richard's many crazy "explanations" are to believed, Oswald must have been some kind of super man, who managed to get to the 6th floor or hide there without Bonnie Ray Williams, or anybody else, seeing or hearing him. Who could hear a broadcast on a radio of a motorbike parked some 150 feet away, from the 6th floor of a building, who could see Jarman and Norman on a sidewalk right below his window without sticking his head out of the window and who managed to run down noisy stairs without anybody seeing or hearing him.
They should make a movie about a guy like that....
