File on 4 Investigates

For 40 years, affirmative action policies were created in the United States to address a lack of women and people of colour in the workplace and at university. They have been questioned before, and are now under scrutiny once again in the Supreme Court.

Two cases are being brought by a group called Students for Fair Admissions challenging the way race is considered in the admissions process at Harvard and North Carolina Universities.

The case against Harvard specifically alleges discrimination against Asian Americans, which the prestigious college denies. But affirmative action is divisive and means different things to Americans.

Nomia Iqbal speaks to Edward Blum, the man bringing the case to court, and to students on either side of the debate.

Is the policy a helping hand, or an unfair handout?

File on 4 investigates claims that children are being taught graphic and age-inappropriate material as part of their Relationship and Sex Education.

The government has brought forward a review into how sex education is taught in schools in England following concerns that children across the country are being taught lessons on oral sex, how to choke your partner safely and 72 genders as part of their RSE.

We speak to teachers, parents, children and sex education providers to try and discover what's really happening in schools and where there are instances of bad practice, we ask if they're part of a systemic national problem in sex education or extreme examples used to push a political moral agenda.

File on 4 investigates the secretive world of oil shipping, dark fleets and camouflaged cargos. Sanctions were supposed to hit President Putin in the pocket, weakening his military capabilities. But have they simply created new markets and new millionaires? And why can a company in Essex enable Russian oil to move around the world without attracting the attention of the authorities?

Britain’s biggest police force says there are hundreds of rogue officers amongst its ranks. It’s now The Met’s job to root them out, with dozens of staff diverted away from organised crime and counter-terrorism units to work in its professional standards department. But can the police be trusted to investigate themselves?

File on 4 can reveal how an officer working for a force outside of London, who had multiple rape allegations against him, was given a job in the professional standards department, investigating complaints made against colleagues. We’ve discovered how complaints to police forces across England and Wales are being regularly dismissed, with many people resorting to legal action to get accountability and winning damages from the police in court.

File on 4 also reveals how recent reforms to the complaints process have done little to improve accountability and restore public confidence.

The Probation Service is meant to protect the public by monitoring released prisoners and offenders on community sentences - helping them to stay out of trouble and rebuild their lives. But a series of catastrophic failures have led to the murders of two women who were killed by men who should have been monitored more closely.

Suicide or attempted suicide is not a criminal offence. But, as Adrian Goldberg discovers, mentally ill people are still being punished for attempts to take their own lives. They can be charged with 'intentionally or recklessly causing a public nuisance,' 'railway trespass' or 'obstruction of highways.' File on 4 hears from people who believe they should have been given care and compassion rather than face criminalisation. The programme also investigates concerns over a scheme called Serenity Integrated Mentoring, or SIM, which was adopted by many NHS mental health trusts in England. It was designed to enable police and hospitals to cope with patients who regularly call the emergency services or arrive at hospitals having self-harmed, attempted suicide, or threatened to take their own life. When tagged under the system, patients can be denied care, prevented from seeing doctors or psychiatrists, and sent home.

A damning report into the culture of London Fire Brigade found a toxic mix of racism, sexism, misogyny and bullying. Launched after a young firefighter of colour took his own life, the review included terrible anonymous accounts from those serving in the capital, women groped during exercises, a black man who had a noose left on his locker.
