I think your summary is probably pretty close, much of it is how it plays out in my mind too. I don't agree that CBC should have heard the tapes first, if they had multiple sources claiming to have heard them, collaborated and then double checked the sources as they claim that they did, I think that they reported responsibly. "This Hour..." has it moments, I do like Marg, she makes me laugh my butt off - always has. Unless CBC is determined to chase this story and hold their position, which appears they are not - or unless someone leaks the tapes, it's pretty much a dead story.
So, let's move onto the next Ford f*ckup.....
