RANGERS supporters can now expect to be targeted by police and "lifted" if they sing anything that can be classed as sectarian.
Celtic fans too will be in the firing line, and every word they utter will be carefully listened to by the cops.
That is one of the outcomes of the soapy summit in Edinburgh, and it seems, on the surface, clear enough.
However, expect the waters to be muddied pretty soon.
What, for instance, will happen in the wake of any arrests that may be made when Celtic visit Inverness on Sunday?
I fully expect a stout defence to be mounted along the lines of, the songs Celtic fans sing in praise of terrorism and the terrorists of the IRA, are not sectarian.
Indeed, it is an argument which has, in the past, already been touched on by senior figures within Parkhead.
Therefore, it would surely be no surprise if Paul McBride QC reaches for his wig and gown and spouts this defence.
Against that, Rangers supporters will be deep in trouble if they are caught singing the banned "Billy Boys," or any other ditty mentioning what they are up to the knees in.
Back in 2006, in the wake of the Villarreal nonsense, in my Sunday newspaper column I warned the Ibrox fans of the danger to their club is they persisted. The slogan I coined was...
FTP! RIP!
Now that danger to Rangers has raised its head again, and that is why Martin Bain was happy to ask Strathclyde Police for a more strict enforcement of the anti sectarian law with regards to singing and shouting.
His action is a measure of just how much Bain wants to weed these people out, and it is to his credit that he is willing to be unpopular with some of the wilder elements of the Rangers support.
I hope he takes advantage of the close presence of the press pack on this Rangers trip to Holland to speak to them and get his message across again... and again.... and again.
He made good points about spikes in crime around the Christmas and New Year period, and may now wish to point to the record of serious crime at the T In The Park music festival.
It is a fact that when there are more people out and about, more people in the pubs, and more drink taken, whether at the Festive Season, a music festival or an Old Firm game, there are more arrests.
Nobody has yet suggested banning Christmas and New Year, far less putting T In The Park on behind closed doors.
That shows just how stupid some of the things that have been written and said about events at Parkhead last Wednesday have been.
Bain is the crucial figure for Rangers now, and something else he should turn his attention to is the make-up of the academic study into the extent of linkage of football to violent crime committed domestically and in the community.
Rangers must dig their heels in and make sure this study is not highjacked by such discredited organisations as, for instance, Nil By Mouth.
The people who are tasked to tackle any such study must be properly qualified, and base their study on empirical evidence and not on anectode, which is just a fancy name for hearsay.
So step forward Steve Bruce, a professor of sociology at Aberdeen University, Tony Glendinning, a senior lecturer in sociology at the same seat of learning, Iain Paterson, a senior research officer at Glasgow City Council, and Michael Rosie, a lecturer in sociology at Edinburgh University.
These men have already destroyed some spurious conclusions about the Old Firm and sectarianism, reached in a haphazard way by Nil By Mouth.
Their input would give any study real weight.
But, after his bizarre performance on Newsnicht, surely there can be no place for Gerry Hassan. Henry McLeish, who also appeared, must have ruled himself out with his muddled performance.
Whatever hymn sheet it was that pair were singing from, though not sectarian or in praise of terrorism and the IRA terrorists, they were both off key and out of tune.
