Why is it a scandal?
The law was changed in 2017 preventing the police from keeping people on bail for more than 28 days except in exceptional circumstances. The Beeb's headline is quite correct:
"More than 93,000 suspected violent criminals and sex offenders have been released without restrictions by police in England and Wales since 2017"
What it neglects to say is that those people were innocent and not charged with any offence. The scandal was the situation pre-2017 when people could be subject to police bail, often with restrictions on their behaviour, for many months or even years whilst the police slowly pursued their investigations at a leisurely pace. A court would not allow the CPS to continually apply for remands and requests to keep someone on bail (conditional or otherwise) for extended periods simply because the CPS has not finished its preparation. Justice delayed is justice denied and that applies equally to defendants as well as alleged victims. The police need to get their act together.
