Fairly horrific new Garda allegations which were cut short in committee published

Backstory: A doctor who spent years working with the Gardai blew the whistle on some new allegations in committee yesterday. He was cut off by the chairman on the grounds that this particular committee hearing was specifically for discussion of the 2005 Act and legislative changes (which is fair enough really, they weren't shutting him down, only trying to keep their meeting on topic as it's a very important topic which keeps getting kicked down the road by the developing situation)
He wrote out his allegations before appearing in committee, and even though he didn't get to read them, the Indo has a copy of his pre-written statement which contains a list of the allegations. For instance:

Indo wrote:

• A young mother recovering from cervical cancer was held in custody for 12 hours.
  
• A senior officer asked him to change his report on an assault by a garda on a man in custody.
  
• A woman went into a diabetic coma after she was refused medical attention.

Further down the article it goes into more detail about the particular case he tried to raise in the committee meeting, of a "special needs" (no further detail given) boy who was allegedly abused very seriously in custody:

In his statement, Dr O'Flaherty, who practised as a GP for 40 years, said the disabled youngster was stripped of his "pants and underpants" and left naked in a holding cell.

He alleges the boy told him both male and female gardai laughed as he was whipped with his belt buckle. The doctor claims the boy's father found him the day he was released with a rope and believed he was going to end his life.

And finally, an allegation that he was pressured into covering up evidence of someone being assaulted in custody:

Dr O'Flaherty also alleges he was told he would "regret" not altering a medical report on an examination of a man who was beaten up by a garda while in custody.

Having read all of this, I'm saddened to find I'm not actually shocked. And that's a serious, serious problem, if this kind of thing has become so normalized by repeated scandals - this kind of thing should rock people to their core, but I suspect many will react as I did, with horror and outrage, but no surprise, no shock.

Presumably this man will be called before the commission of investigation into the Guerin findings. I'd hope also that he's passed these allegations on to GSOC, and I'm usually no fan of the Indo but fair play to them for publishing the story.

I have nothing against the committee chair for insisting that the committee remain on topic, I imagine some will rush to attack this decision but to be fair, we'll never sort out this whole mess if every issue that needs to be looked at ends up being sidelined by the more sensational issues. Important though this story is, equally important that all aspects of the Justice scandal are given equal time and aren't crowded out by one another. There was a huge reaction on Twitter yesterday condemning the committee for not allowing him to read his statement in full, IMO that's misdirected but that's just my opinion - regardless, this opens yet another disturbing new chapter in what's rapidly becoming one of the biggest scandals in the history of the state.

Sadly, I've seen and heard nothing which would give me any confidence that we've moved any further than the tip of the iceberg

Would cameras / microphones in Garda stations, vehicles and cells incur data protection breaches or are they a potential option? Before anyone mentions cost, cameras and microphones of various qualities are dirt cheap these days so I doubt that's a legitimate reason to hold off on it. Of course, that won't stop "blind spots" being found which seems to almost happen in other countries where they do have surveillance of police stations, schools, hospitals and other places where abuse might take place, but at least it'd be something, right?
Committee and gov't are already looking at dramatically strengthening GSOC's powers, predictably AGSI has already slammed the proposals after repeatedly attacking GSOC in recent weeks - their position is rapidly turning into a PR disaster for them given the tsunami of scandals over the last few months and even just this last fortnight, any suggestion by them that GSOC's powers need to be reigned in rather than expanded just looks (IMO) ridiculous. What else can or needs to be done? I don't think I'm exaggerating when I say that general faith in the justice system is deteriorating rapidly day by day. Does the DPP / judicial system need a shake up as well? I've always thought the DPP is a little unaccountable and there seems to be a massive amount of power over justice concentrated in that one office. Sentencing guidelines seem to be on their way, but I wonder if the issues with the judiciary, particularly when it comes to dealing with Gardai convicted of offenses, are more cultural than legal, in which case they're far harder to solve.

What needs to be done in order to start drawing a line under this sorry chapter in Irish history?
