Fighting knife crime before it happens; Scotland's "not proven" verdicts; and the law on automated cars. Knife crime in England and Wales is at its highest in ten years. Some young people can find it hard to resist gangs or knives for what they see as self-protection. Often they end up in the criminal justice system. Some argue the law is not the answer. But what is the alternative? We hear from a youth worker at the successful youth centre Youth Futures, and from a retired senior criminal barrister, who has launched an online one-stop-shop, fightingknifecrime.london, for those seeking or offering help to keep young people out of trouble. In Scotland, juries can find defendants guilty, not guilty or not proven. If guilt is "not proven", the defendant is acquitted and regarded as innocent in law. Should that third option be abolished? Juries often use "not proven" in rape cases, if they feel guilt has not been proven 'beyond reasonable doubt' (the requirement for a guilty verdict) but nor do they want to imply they disbelieved the alleged victim. Now some campaigners want to abolish the "not proven" option, as research has shown that if it didn't exist, more juries would find the accused guilty, even in rape cases. The government has announced that cars will be allowed to steer themselves in slow-moving motorway traffic, so long as they had been approved for use with automated lane-keeping systems. But what does the law say about liability for automated vehicles? Who is responsible if there is an accident? Is it the driver or the car manufacturer? What changes are being introduced by this year's Automated and Electric Vehicles Act and the planned changes to the Highway Code?

It’s illegal to ride a private e-scooter on public roads or pavements – but the rules for the new, council approved e-scooter rental schemes are different. We navigate the maze of laws and regulations to ask what’s allowed, required or illegal. Billionaires are about to fly into space, but what is the legal framework for this? What if your rocket hits my satellite? We boldly go into space law. Why coal tip laws brought in following the Aberfan disaster do not protect the public and need to be reformed. And the changing face of the legal profession – criminal barrister Mark Robinson shows that lawyers come from a greater range of backgrounds now – he didn’t have any GCSEs, but a career as a DJ.

Thousands of people have received fixed penalty notices for breaching Covid-19 restrictions, even though no offence had actually been committed in their cases. Yet there is no appeals procedure, and not paying the fines risks a criminal record. So what should happen with them? Sir Geoffrey Vos, the master of the rolls and head of civil justice, reveals how new online systems are increasingly doing away with the need to go to court. The legal profession used to be dominated by middle-aged, middle-class, white men, but that has been changing, and this year I. Stephanie Boyce became the first person of colour to be elected president of the Law Society, the professional body for solicitors in England and Wales. What are her priorities for her tenure? The recent quashing of the convictions for theft and false accounting of 39 sub-postmasters after Britain's biggest miscarriage of justice has laid open the world of private criminal prosecutions. It was not the Crown Prosecution Service that took the sub-postmasters to court, but the Post Office itself. Should private prosecutions now be regulated?

Traumatic brain injury can cause neurological changes that make people more impulsive, less able to control their reactions, and less able to understand others. Therefore it's associated with violent crime. An estimated 60% of those in prison have a history of brain injury. But is prison the best place for them, and their rehabilitation? The criminal justice system is taking an ever greater interest in how to deal with traumatic brain injury. We hear about a Thames Valley Police pilot project to keep offenders out of prison, pre-sentence screening in the UK and elsewhere, and about an innovative court for those aged 18-25 in New Zealand. Brain injury is as common among women prisoners, often due to a history of suffering domestic violence. For these women their injuries, compounded by other factors, lead to mental health issues so serious that it's estimated that three quarters of them have tried to take their own lives. What are prisons doing to help them? And what about women prisoners' additional burdens, such as anxiety about separation from their children, which affects them more than men? Can a new report by the Chief Inspector of Prisons point to ways forward for England and Wales? Presenter: Joshua Rozenberg Producer: Arlene Gregorius Researcher: Diane Richardson

Judicial Review is a mechanism to check the legality of decisions or actions by public bodies such as the government or parliament. But has this turned into "politics by another means"? The government commissioned Lord Faulks and a panel of experts to examine this question, and to make recommendations for reform. The report was published last week. But does the government now want to go much further than the recommendations in the report? Should there be legal aid for bereaved families whose relative died in the care of the state, such as in prison, a police cell or in a mental health in-patient setting? These deaths trigger "Article 2 inquests", referring to the right to life, protected under the European Convention on Human Rights. The coroner will want to find out what went wrong, so it doesn't happen again. The state has legal representation to defend itself, but the families often can't afford the specialist lawyers that, campaigners argue, are required for a level playing field. Family breakdown can mean former partners end up in court to try and resolve disputes. This can be time-consuming, with long delays, and be very costly. Could family arbitration be the solution? We eavesdrop on a mock arbitration to find out how it works. And how much cheaper are they really? Which UK elections can EU citizens vote in, and in what parts of the country? The answer is surprisingly complex for the votes in May - and will become more so in future elections.
