There's two different strands to this. Yes, the Club/Board could have done more over many years to highlight the imbalance, the unjustness, the persecution of our fanbase etc. I doubt anyone would question that.
However, to try and deflect from the fact that many - it wasn't just UB08 obviously - were singing songs they knew were likely to get us into trouble by laying the blame at the feet of the Board for inaction on previous incidents doesn't sit well with me at all. We fans know - and have known for years and years - that the time was coming when we got hammered for this. Certainly in Europe and, most probably in the near future, in Scotland too. A cosy wee chat between King and UB08 suggesting they don't sing about '19th Century Terrorist bastards' would have changed what precisely? It would have made not a bit of difference. Its not 'leadership' that is/was required its common sense. I'm sure you've read the thread on how the NI fans addressed the issue - it was, almost exclusively, fan driven. That's what's needed here not 'leadership' from Dave King.
@sherbrook_loyal isn't too far off the mark with his thread but, I suspect, it is likely to fall on deaf ears.

That's not to say that the Board shouldn't do more to engage with the fans - but I see that as a much wider issue, covering many, many more topics than simply the signing of songs that have no place in a football stadium.
