I have trouble believing that this is something the Mayor "randomly dredged up in the past few weeks". My impression of that Conrad Black interview was that it was rehearsed, if not scripted to some extent. Unless he's delusional, Rob Ford knows that most of what he said about the Daniel Dale incident is provably wrong. So why would he choose to bring up this particular incident and frame it in this particular way? If it was a spontaneous outburst, I could understand that, but it didn't seem spontaneous at all. It seemed very deliberate (even to the point of not saying "that word").
Why is Ford going after Daniel Dale? I would have thought that there were other reporters who would be much higher up the list of people the Mayor would like to get removed from reporting on him. And why would he do it now, so long after the episode? Bringing it up again just gives everyone a chance to go over the details. And those details look even worse when viewed in light of everything we now know. Now that we've seen the "I'll rip his throat out" video, a raging Rob Ford is so much easier to picture.
Did Daniel Dale do something particularly harmful to the Ford brothers?
