Tied up with the whole 'misogyny in the police' issue is the case of Emma Caldwell.
This time it's Strathclyde Police in the spotlight.
Emma was murdered in 2005.
After the death of her sister, she'd spiralled into depression, followed by drug addiction, and became a sex worker to pay for that.
Ian Packer was a violent scumbag and prolific user of prostitutes. Sex workers in Glasgow all knew about him and most feared him due to the sexual violence he liked to inflict.
When Emma was murdered, Packer soon became a prime suspect for some of the low-ranking investigating officers, following numerous statements from fellow sex workers. But their requests to arrest him and bring him in for questioning were denied by more senior officers. One of the officers who tried unsuccessfully to have Packer detained has said he was told by the leading senior investigating officer on the case, Willie Johnson, "when you get Iain Packer and bring him in, it doesn't matter what he tells you - he won't ever be an accused in this case". Packer was asked for a statement on several occasions (and first denied knowing Emma, but then changed that) but it was never followed through and he was never arrested. Johnston left the police force the following year.
Instead, Johnston and other senior officers focused on four Turkish men. They tried to fit them up, but the case collapsed. What their motivations were to ignore the main suspect (despite building evidence, albeit mostly circumstantial, against him) and pursue four innocent men, we'll never know (but can speculate, and there's accusations of racism been bandied around involving the senior officers)
It was the BBC who helped get him convicted. He gave an interview as part of a documentary they did about Emma and the BBC interviewed many other women. They found that he was a violent sex offender that had committed at least 20 rapes or violent sexual assaults after the initial bungled investigation.
20 needless additional victims of this piece of shit. And all because a group of senior police officers failed in what should have been a simple case to solve (or were just corrupt)
