A rape case, a U.S. airbase and the accountability gap inside Britain’s “base justice” system

When a British woman called 999 in June 2020 and reported that a U.S. airman had raped her in Suffolk, she entered what she believed was the ordinary criminal justice system of England and Wales: local police, a sexual assault referral centre, a crime reference number and an independent adviser meant to help her navigate what came next.

That assumption lasted less than three weeks.

According to a new Guardian investigation published Thursday, Suffolk police transferred the case against Tyrion Davis, then a 22-year-old senior airman in the U.S. Air Force stationed at RAF Lakenheath, to U.S. military authorities 20 days after opening the investigation. The decision meant Davis was not tried by a British jury in a crown court for alleged offences said to have occurred while he was off duty at his home in Brandon, near the airbase. He was instead prosecuted by court martial at RAF Lakenheath, inside the American military system.

The case has become the sharpest example yet of a larger accountability problem: serious alleged crimes involving U.S. service members and British victims can be handled behind the perimeter of U.S.-operated bases, under rules most people in the surrounding communities never see until they collide with them.

Davis denied wrongdoing and maintained that his sexual encounters with the two British women in the case were consensual, according to court documents cited by the Guardian. A military panel acquitted him of 10 further counts of sexual assault and abusive sexual contact and two counts of assault. But it convicted him of one count of sexual assault under Article 120 of the Uniform Code of Military Justice, involving non-consensual penetrative sex against his estranged wife, identified by the Guardian under the pseudonym Emily. Davis was sentenced to 10 months’ confinement, dishonourably discharged from the Air Force and placed on a sex offender registry, where the Guardian reported his status is now listed as “absconded.” His conviction was upheld by a U.S. Air Force appeals court in January 2024.

The legal category matters. The Guardian reported that the conduct for which Davis was convicted — “penetrating her vulva with his penis, without her consent,” as the military charge described it — would likely have been charged as rape in England and Wales. The Sexual Offences Act 2003 defines rape as intentional penile penetration of the vagina, anus or mouth of another person without consent and without a reasonable belief in consent. In the U.S. military code, Article 120 separates “rape” from “sexual assault” and includes, under sexual assault, committing a sexual act upon another person “without the consent of the other person.”

That difference is not just semantic. Under the English system, the Guardian reported, sentencing for the likely comparable offence would have been determined by a judge under guidelines ranging from four to 19 years, with a statutory maximum of life imprisonment. In the military system, the possible maximum for Davis’s conviction could have reached 30 years, but sentencing was left to the same panel of officers and airmen that decided guilt. Davis’s defence lawyers recommended 30 days. The panel gave him 10 months.

For Emily, the sentence was a measure of how the system valued what had happened. “He could have had 30 years, but he got 10 months,” she told the Guardian. “Ten months is a slap on the wrist.”

What the transfer changed

The British woman who first went to police, identified by the Guardian as Rebecca, said she was told the U.S. route would be faster. Six days after her initial report, she said, Suffolk police called to say American authorities had requested jurisdiction and that the transfer would provide a quicker path to justice. Her independent sexual violence adviser, employed by Norfolk police, made a similar argument, according to Rebecca’s account: the Crown Prosecution Service might not take the case; if it did, a British court date could take at least two years; the Americans had said a court martial could happen in six months.

Rebecca agreed. The case was formally handed to the Americans on June 29, 2020. The promised six-month timetable became a two-year wait, and Rebecca told the Guardian she dropped out of her midwifery degree while the case dragged on.

The transfer also changed the courtroom. In a British court, sexual offence complainants can often give evidence using special measures, including screens or video links. Rebecca said she could not testify from behind a screen at the court martial and had to answer questions in a small courtroom at the base with Davis metres away. She said she removed her glasses so she would not have to see him clearly.

Days before testifying, Rebecca said, she was advised by her U.S. Air Force-appointed legal representative about how to dress: do not wear red lipstick, avoid red, wear black or white, “if anything, wear white because it’s more angelic.” The detail lands like a small object from a much bigger machine: a survivor navigating a justice process that appeared to treat optics, deference and military culture as part of the trial environment.

Emily described her own testimony as intense and invasive. She was five months pregnant when she gave evidence over two days. Court documents cited by the Guardian show Davis’s lawyers argued she had fabricated allegations after an affair with one of Davis’s Air Force colleagues and wanted to change the narrative “from unfaithful wife to victim of sex assault.” Emily admitted during cross-examination that she had initially lied about the affair, but said it did not alter the assault. “Even if I had been having an affair the whole time, it wouldn’t have justified what he did,” she told the Guardian.

The jury was not a civilian jury. It was an all-military panel. Rebecca said she learned only about a week before the court martial that Davis’s peers would decide the case. “It’s like, if I did something wrong outside of work, having all of my nursing colleagues being on the jury,” she told the Guardian. “It doesn’t make sense.”

The agreement underneath the case

The jurisdictional machinery sits inside the NATO Status of Forces Agreement, signed in 1951, and domestic implementing arrangements including the U.K.’s Visiting Forces Act 1952. The NATO text gives the “sending State” — here, the United States — the right to exercise criminal and disciplinary jurisdiction over people subject to its military law while in the “receiving State,” here, the United Kingdom. It also gives the receiving state jurisdiction over offences committed on its territory and punishable under its law.

The crucial hinge is concurrent jurisdiction. Under Article VII of the NATO agreement, the sending state has the primary right over offences solely against its property, security, personnel or dependants, and over offences arising from official duty. “In the case of any other offence,” the agreement says, “the authorities of the receiving State shall have the primary right to exercise jurisdiction.” If the state with the primary right decides not to exercise it, the other can proceed; the state with the primary right must give “sympathetic consideration” to waiver requests in cases the other state considers particularly important.

The Davis case, as reported, involved alleged off-duty conduct at a private home in Suffolk and British complainants. That makes the public accountability question unavoidable: why did British authorities cede the case, and what exactly was Rebecca told before she agreed?

Suffolk police told the Guardian that jurisdiction was transferred to the U.S. Air Force with Rebecca’s “agreement,” after a discussion involving her, an independent adviser and Air Force legal services. The force did not directly respond to Rebecca’s complaint that she had not been fully informed of the implications. It said it was committed to ensuring its actions were led by victims’ wishes and best interests and was “keen to understand examples where this is not the experience of victims.”

Norfolk police, which employs the adviser who worked with Rebecca, was more direct. A spokesperson told the Guardian: “We recognise the victim’s lived experience and are sorry she feels she was not fully informed about aspects of the military court process before making her decision.” The force said it would reflect on the case to ensure victims receive the clearest possible information.

The U.S. Air Force’s military police told the Guardian that, as an investigative agency, it could not respond to questions about “decisions around jurisdiction, charges, and legal proceedings” and said those questions should be directed to the proper authorities. Davis did not respond to the Guardian’s requests for comment.

A wider pattern, not a one-off

Thursday’s story follows a Guardian “Base justice” investigation published last month that identified a range of convictions of U.S. service members in Britain, including sexual assaults, child sexual abuse offences, indecent exposure, violent attacks and motoring offences. The Guardian reported that many were prosecuted in American courts martial held on U.S. military bases, not in British courts open to the public in the ordinary way.

That matters because the United States has a large military footprint in Britain. The Guardian reported that more than 12,000 U.S. personnel are stationed on at least 15 U.S. bases and facilities in the U.K., with all but one in England. For towns around RAF Lakenheath, RAF Mildenhall and other installations, the practical question is not abstract sovereignty. It is whether a resident who reports an alleged violent or sexual offence can understand, in real time, which justice system will take over, what rights and protections will follow, who will decide guilt and sentence, and how much of the process will be visible to the public.

The Davis case also echoes the case of Capt. Jacob Wulfson, a U.S. fighter pilot at RAF Lakenheath who, according to the Guardian, avoided a British trial after strangling a woman in his Cambridge apartment in 2023. Wulfson was acquitted of a separate sexual assault charge involving an allegation of non-consensual penetration that, as in Davis’s case, was not charged as rape. Sarah Steele, the Cambridge academic who was the victim in the strangulation case, told the Guardian last month that the court martial process was degrading. The case prompted cross-party concern in Westminster, and David Lammy, now the U.K.’s deputy prime minister, asked the U.S. government for a full account of what happened.

None of that means every court martial is unfair, or that every transferred case would have produced a different outcome in a British court. It does mean the transfer decision itself deserves scrutiny as a public act, not a quiet administrative handoff.

The accountability questions now

The core issue is consent — not only in the criminal allegations, but in the justice process that followed. Rebecca’s agreement to the transfer is now central to the official explanation. But meaningful agreement requires more than a yes given during trauma, especially when the person is being told one route may be faster, more supportive and more likely to produce action.

The public record now supports several questions for Suffolk police, Norfolk police, the Crown Prosecution Service, the Ministry of Defence and U.S. military authorities.

First: what written guidance governs decisions to waive British jurisdiction in alleged serious sexual offences involving U.S. personnel and British civilians? Second: are complainants given a standardized, plain-language comparison of the British criminal process and the U.S. court martial process before being asked for a view? Third: who records that advice, and is it auditable later? Fourth: do U.K. police forces track how often they cede cases involving visiting forces, what categories of offences are involved and what sentences result? The Guardian reported in June that British police and prosecutors do not keep statistics on such refusals.

That data gap is its own accountability failure. If no one counts the handoffs, no one can honestly tell Parliament, victims or local communities whether they are rare exceptions, routine practice or something in between.

The stakes are not anti-American theatre. They are basic rule-of-law plumbing. A justice system loses legitimacy when the public cannot see how serious cases are routed, when victims say they did not understand what they were giving up, and when the difference between an open civilian courtroom and a fortified base courtroom is treated as a technicality.

Rebecca did what the system asks complainants to do. She called police. She gave evidence. She handed over devices. She went through forensic examination. She testified. Emily did the same inside a military process whose panel convicted Davis on one count and acquitted him on the rest. The question now belongs to the governments and institutions that built the route: if Britain has the primary right to prosecute many off-duty crimes on its soil, why are some of the most serious cases still disappearing behind the wire?
