Sure, Lodown, I can see there would be the possibility of things getting too 'matey' depending on personalities and individual integrity.
It's a complex issue, of course, but the current climate of mistrust, blame and double standards feels all wrong.
How to fix it is another story - big root-and-branch changes could only come with sufficient political will, and I doubt there's enough votes in it to make ministers sit up and take notice, even when aeroplanes crash. There's a bit of media frenzy for a while, then we return to the status quo.
