EDINBURGH (Edinburgh Daily) October 16, 2026 –

Four serving and former Police Scotland officers have been publicly identified as sexual predators and rapists within a four-month period, sparking widespread public outrage and intense scrutiny over the force’s internal vetting procedures.

The exposure of the four men—Campbell Petrie, Carmichael John Williamson, Cameron Ross, and Alan Greer—has brought renewed focus to the national police service’s handling of misconduct and violence against women.

What Are the Details Surrounding the Recent Court Sentencings?

As reported by Victoria Pease of STV News, former Police Scotland sergeant Campbell Petrie, 50, was handed a 15-year extended sentence—comprising 12 years in custody and three years of extended supervision—at the High Court in Glasgow.

Petrie was convicted of nine charges of physical and sexual abuse committed between 2006 and 2023, including the rape of two women, one of whom was a serving police colleague whom he attacked while she was asleep.

Passing sentence at the High Court in Glasgow, Judge Alastair Watson told Petrie:

“The gravity of this sustained course of criminal conduct cannot be overstated, and it is my duty to impose a sentence which reflects its seriousness and its persistence.”

Judge Watson further described Petrie’s continuing denial of guilt during post-conviction interviews as “bizarre” and “disappointing”.

In a separate trial at the High Court in Edinburgh, serving constable Carmichael John Williamson, 32, was convicted of four charges, including three counts of rape and assault against a teenage girl and an adult woman in the Shetland region between 2014 and 2022.

As reported by Oliver Partridge of GB News, Williamson denied all charges, claiming during his testimony that he had no recollection of recording sexual acts or assaulting the victims.

Williamson was placed on the sex offenders’ register and remanded in custody ahead of his sentencing scheduled for December.

How Did the Previous Cases of Cameron Ross and Alan Greer Unfold?

As reported by Paul Kelly of Bauer Media, former officer Cameron Ross, 39, was sentenced to 10 years in prison at the High Court in Edinburgh after being found guilty of raping two women and subjecting a third to abuse over a ten-year timeframe in Stornoway and Inverness.

Ross was convicted of rape, domestic abuse, attempting to pervert the course of justice, and threatening behaviour.

In July, details emerged regarding PC Alan Greer, 47, who ended his life following his arrest for serious sexual offences, including rape and attempted murder.

As reported by Mark Daly of BBC Disclosure, an investigative probe revealed that Greer had managed to pass initial police vetting checks despite having prior criminal reports filed against him regarding his behaviour towards women.

What Response Has Police Scotland Provided to the Convictions?

Following the sentencing of Campbell Petrie, Police Scotland issued an official response regarding the conduct of its former officer.

Assistant Chief Constable Tim Mairs, who leads on Major Crime and Public Protection for Police Scotland, stated:

“Petrie committed a series of severely abusive, exploitative and violent crimes towards women. His offending is in stark contrast to the professionalism and commitment of the officers who investigated him and ultimately helped bring him to justice.”

Assistant Chief Constable Mairs added that the force remains committed to investigating allegations regardless of the perpetrator’s status:

“This investigation shows the public that when matters of this nature are reported to us – regardless of who the perpetrator is – that victims are listened to and supported as we take immediate action to identify and investigate those responsible.”

Similarly, Detective Superintendent Stevie Bertram of Police Scotland’s public protection unit addressed the conviction of Carmichael John Williamson.

Detective Superintendent Bertram noted:

“Reports of violence against women and girls are rising and it is of the utmost importance for Police Scotland to play its part in tackling this national emergency. Our thoughts are very much with the victims in this case, and I wholeheartedly commend their strength in reporting these crimes.”

What Institutional Failures Have Been Identified in the Vetting Process?

Court proceedings and investigative disclosures revealed that several of the convicted officers continued to serve or receive promotions despite early warning signs.

It emerged after Campbell Petrie’s conviction that he had first been arrested in 2009 over allegations of threatening behaviour towards a woman, but the case was ultimately dropped by prosecutors.

Petrie was subsequently promoted to the rank of sergeant and continued his employment with Police Scotland before being arrested, charged, and suspended in December 2023. He formally retired from the force in December 2025 prior to his trial.

Similarly, BBC Disclosure highlighted that Alan Greer maintained his position within the force for years while committing sexual offences across a 14-year period.

Reports indicate that up to 50 Police Scotland personnel—comprising 45 constables, six sergeants, and two inspectors—are currently suspended on full pay pending ongoing investigations into allegations related to violence against women and girls.

Background of the Particular Development

The series of convictions comes amidst broader statistical increases in reported sexual offences across Scotland. Figures released by official authorities showed that the number of rapes and attempted rapes reported in Scotland rose by almost one third over four years, reaching 3,240 reported incidents in the year to June 2026.

Women’s advocacy groups and civic organisations across the country have formally classified the rise in gender-based violence as a “national emergency”.

In response to historic misconduct scandals across UK policing, Police Scotland initiated enhanced anti-corruption measures and systematic re-vetting programmes. Approximately 8,000 officers and staff members were designated for updated background checks to identify individuals with unaddressed criminal allegations or integrity risks.

The recent court cases represent the culmination of internal public protection unit investigations into long-standing complaints.

Prediction: How This Development Can Affect the Scottish Public and Police Force

This series of convictions is expected to have direct consequences for both the general public in Scotland and the operational framework of Police Scotland:

1. Erosion of Public Trust: The exposure of multiple high-ranking and long-serving officers as violent offenders is likely to deepen public skepticism toward law enforcement, particularly among female victims of crime who may feel hesitant to report domestic or sexual abuse to serving officers.
2. Overhaul of Police Vetting Procedures: Police Scotland and oversight bodies such as the Scottish Police Authority (SPA) will face intensified pressure from the Scottish Parliament to implement stricter, continuous vetting checks. Historical immunity granted by dropped charges or internal resignations is expected to be replaced by mandatory re-screening protocols.
3. Pensions and Administrative Reform: Following Campbell Petrie’s sentencing, legal and administrative mechanisms regarding the forfeiture of police pensions for officers convicted of serious criminal offences committed during service are likely to be reviewed and enforced more rigorously.
4. Increased Scrutiny on Suspended Officers: With approximately 50 personnel currently suspended on full pay, parliamentary committees and taxpayer advocacy groups will likely demand faster misconduct panels and legal processing to resolve outstanding allegations without prolonged public expenditure.
