There were no news cameras to witness someone pacing back and forth in an upstairs window.
Perhaps, perhaps not. It doesn't seem like there is any surviving video/photographic evidence (if, I happily concede, there ever was any).
But the police statements and reports themselves suggest that such a thing (or a variant of it) was the exact reason why it took so long for them to enter the house. It's entirely possible, of course, that this scenario was being reported verbally, in radio news, or even as part of television news (but without visual footage), which matches the excerpt from Michelle's comments you have posted.
Firstly, she says " began to
listen in more closely - it is during this
listening that she reports hearing the information about the police being outside with Jeremy, someone pacing around inside with a gun, and police officers trying to speak to someone inside the farmhouse.
All of that, to my knowledge, appears in the various statements. She then says, "I watched for an hour or so...."
So that would match the time of Breakfast TV coming on at 6.30 - by the time she had to go to bed, "there was no resolution" - if Michelle stopped watching at around 7.30 and went to bed, there would have been "no resolution" by then.
Back in 1985, my alarm for getting up in the morning was the radio. We had to wait for breakfast TV to
see breaking stories we may have heard some hours earlier on the radio (I got up at 5am in those days.)
While Michelle's account may seem "false" by today's standards of 24 hour, worldwide, instantly accessible news, her account is entirely in line with 30+ years ago news coverage.
