From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Head injuries can dramatically increase the chances of someone committing violent crime, a study has found.

In a group of 22,914 traumatic brain injury victims, almost 9 per cent went on to commit acts of violence after diagnosis – three times the rate in the general population.

The British and Swedish scientists who carried out the research defined violent criminals as those convicted of homicide, assault, robbery, arson, sexual offences, or illegal threats or intimidation. Epilepsy was also investigated as previous studies had suggested it can increase the risk of violence, but scientists found no significant association between it and violent crime.
