When Ulster Unionist MLA Mike Nesbitt breached the Covid-19 regulations he immediately admitted his offence and swiftly resigned his chairmanship of the Executive oversight committee in the Assembly. At the time Michelle O'Neill declared that: "We're in difficult times, but none of us are exempt from these regulations."
How right she was.
But it is a pity that she hasn't applied those words to herself and followed Nesbitt's honourable decision and resigned her own position as Deputy First Minister, or at least stepped aside temporarily until the mess she helped to create was cleaned up.
Mrs O'Neill, as Deputy First Minister, made a deliberate choice to attend the west Belfast funeral of her friend Bobby Storey, knowing that it was alleged that he was the IRA's chief of intelligence and mastermind of the break-in at Castlereagh police station in 2002 to steal sensitive files relating to police personnel and informers.
He was also allegedly the chief planner behind the IRA robbery of £26.5m from the Northern Bank in December 2004.
Both of these high-profile incidents were at the time very damaging to the peace process and, in particular, power-sharing at Stormont.
Indeed, they may well have been carried out to sabotage the out-workings of the Good Friday Agreement. The Assembly is now having to wrestle with the political fallout from this stage-managed republican funeral.
The funeral was rightly regarded by all except Sinn Fein as having breached the public health restrictions on social distancing.
The fact is that Sinn Fein urged the general public to attend along the route of the funeral.
It encouraged its own members to turn out in west Belfast and, indeed, told them to follow a black-and-white dress code.
The massed ranks of republicans in their distinctive dress was an arrogant display of their might and power in west Belfast.
It had all the hallmarks of an IRA funeral, without the black berets and balaclavas. That was its political objective.
It was staged for visual effect without concern for the public health regulations or the health and welfare of the community in west Belfast.
The irresponsible charade of marching hundreds of people down the Andersonstown Road to the republican plot in Milltown Cemetery, knowing that the deceased was to be cremated at Roselawn was not simply bizarre, but a deliberate demonstration of the militaristic character of the event.
At its heart Sinn Fein is still a militaristic organisation that honours the IRA as a legitimate military force. The shadow of a gunman still haunts that party.
Sinn Fein has an internal culture which warps its thinking. It does not consider its aberrant behaviour as being outside the law, because it regards itself as the law.
Sinn Fein has been foremost in insisting on the public health restrictions being strictly in place for as long as possible, though when it came to Mr Storey's funeral the restrictions went out the window.
Its leadership has, rightly, faced massive public and political criticism for failing to comply with the rules.
As the SDLP's Patsy McGlone said: "To many people, it seemed that they were saying: 'Do what I say, not what I do.'"
The obvious failure to be socially distant at the funeral and not to obey the rules was so blatant that those previously affected by the deaths of loved ones killed by the virus were outraged and protested with great passion.
So much so, despite initially stonewalling and saying that this was just "political point-scoring", Mrs O'Neill and Mary Lou McDonald rowed back and gave public apologies, although these were generally considered to be half-hearted.
Mrs O'Neill is totally isolated on this issue and has succeeded in uniting all the other parties in the Assembly against her.
Given the brittle politics of Stormont, the very continuance of the Executive is now under growing stress and, as she refuses to relent, the crisis deepens.
And it may well be, given the gravity of the situation, that the only solution is for Mrs O'Neill to step aside temporarily until the dust settles on this self-created crisis.
Mind you, the thought of a suitable alternative to her is pretty scary, given the scarcity of talent within its ranks.
Imagine the gaffe-prone Conor Murphy becoming Deputy First Minister, or Martina Anderson, the former "outreach officer" to unionists, taking the reins of power in Stormont.
But at the heart of this matter is Sinn Fein's continued failure to purge itself from the culture of the IRA and to democratically reconstruct itself.
The existence of the Army Council is no myth, as the PSNI and Garda have both confirmed.
Until its paramount role is ended, Sinn Fein will never be a normal political party.
