Good show, Russell.
For me, the Herald's entire week focusing on domestic violence was soured by two articles that opened the series: Tony Veitch's piece, and Kerry McIvor's piece where she more-or-less said, "Why don't they just leave?" There was some really good work later in the week, but I found it hard to give it much weight, given those opening pieces.
The other thing that I thought could have been very useful was some serious statistical work, to examine the truth of the "she does it too" claim. It would take someone sitting down with the various articles and research reports on domestic violence, and analysing them, in a metastudy, and then reporting on it for a general readership, not just academics and people working in the area. But perhaps the Herald doesn't have the resources to do this. Even so, as one of the guests on your show said, it's a line that's trotted out again and again, to excuse domestic violence, and it would be very helpful to have some testing of that claim.
