SPR
Whilst sharing the disappointment expressed here, I'd be reluctant to give any tacit or overt support to urging action by stewards or police. I think we have been vilified too often in the past and this sort of intervention may just exacerbate the situation. It also helps reinforce the creeping criminalisation of free-speech, so beloved of many Tartan Politicians.
Continued exhortation to toe-the-line is my preferred solution; whilst maintaining a vigorous rebuttal of any attempt to push us any further..
