Belfast City Council's internal report notes that Bobby Storey's hearse arrived at Roselawn Cemetery at 15.54 and that CCTV footage shows it leaving 24 minutes later.
Dissecting the details of somebody's cremation is an unsightly business. Sinn Fein gave the IRA leader a public funeral, but his cremation should have remained a private matter for his family and friends.
The only reason that justifies it being scrutinised is the disgraceful discrimination against eight ordinary families whom the council effectively made sit at the back of the bus.
It can never be put right no matter how loudly City Hall apologises or what compensation is paid. It's not like messing up a birthday, anniversary or some other occasion. It doesn't get more traumatic than a funeral.
It's hard enough to summon the strength to stand in that cemetery and say a final goodbye to someone you loved. To find out that the person precious to you was denied the same rights as another who was deemed more important is a body blow from which it's hard to recover.
Sinn Fein says that such discrimination was the last thing Bobby Storey would have wanted because he was committed to equality, so it's hard to fathom why the party doesn't back an independent investigation into events.
It wasn't Sinn Fein that made the decision not to let these families have the 30 mourners that Bobby Storey (right) was granted.
If there is nothing to hide, then support an impartial outside investigator looking at it all. Sinn Fein usually rejects internal inquiries as inadequate on a whole range of issues. Why is that not the case now? It is wholly inappropriate that the institution responsible for the wrong at Roselawn is the only one allowed to investigate it.
If Sinn Fein is genuinely angry on behalf of the families treated unequally, then why isn't it demanding that those corporately responsible are held to account and face censure?
The party is singing the praises of council chief executive Suzanne Wylie and director of city and neighbourhood services Nigel Grimshaw, so who does it blame for the hurt inflicted on these families on June 30?
Why is the party talking about a "witch-hunt" rather than asserting that truth and transparency are vital for public confidence?
For me, the issue is not what happened inside the cemetery after Bobby Storey's hearse arrived.
I don't buy into the wild claims that republicans took control of the cemetery or that staff were intimidated and harassed. I think that's a ridiculous sideshow.
There were no paramilitary trappings at the funeral. Neither was there a flag nor guard of honour. Some of those who would be outraged at the idea of a tricolour in Roselawn don't have a problem with various loyalist emblems on display there. Much of the feverish speculation comes from those who just don't want a republican about the place.
The chain of events leading up to the cremation is where the focus should be. Why, for example, did Sinn Fein twice ring Ms Wylie the week before the funeral?
The report says that the caller requested details of the numbers who could attend the cremation.
Why did they do that? Funeral regulations were already in the public domain - they're published on the Executive's website. Any Sinn Fein elected representative would have known that. If in doubt, they could have checked with their party's own ministers. Why involve the council's chief executive? Who in Sinn Fein made those calls?
An independent investigation must focus not just on how senior council officers behaved but on what interventions, if any, were made by members of Belfast City Council or other politicians.
City Hall's internal report says that the decision to let 30 mourners into the Storey cremation, which was denied to the eight families earlier ones that day, was made by the director of city and neighbourhood services, the former PSNI commander Nigel Grimshaw.
The internal report is vague on why he did so. Apparently, he made an "operational decision" and decisions were taken "in the context of managing potential issues if numbers arrived and demands for access were made".
Is that a roundabout way of saying he feared a riot? If so, that means that somebody reckoned that mourners for the previous eight cremations would be less assertive about getting in - and that worked against them.
The report says there appears to have been a focus of Storey's funeral "as a profile event", but death should know no VIPs.
The image I can't get out of my head is of nurse Lynn Paul breaking down in tears during a UTV interview.
She explained how she wasn't allowed into Roselawn for her mother's funeral on the same day as Bobby Storey's.
"It's not nice to watch a hearse drive away from you thinking, 'That's my mummy in the back... she raised me, she cared for us'," Lynn said.
She accepted the situation because she thought that the same rules applied to everybody. She felt heartbroken and humiliated when she found out that was not so.
"How can one person or one family matter more than the rest? For my family, we feel like we don't matter. I feel disgusted and angry - really, really angry," she said.
Those emotions about events at Roselawn Cemetery are entirely justified. The gates should either be open or locked to all. Nobody should be left to stand alone outside.
