ELI5: The legal concept of bail. How can a court justify releasing a potentially harmful person for a large sum of cash?

You'd had a response from a US perspective, so I'll give you the UK answer.

Here, as in the US, it still comes down to being innocent until proven guilty - therefore, if you're awaiting trial you should remain free.

However, we will put restrictions on someone on bail - we won't insist on money like in the US, but the court might insist that they report to the police daily/weekly/whatever, remain at a certain address or perhaps surrender their passport.

That said, if someone has been charged with a particularly serious crime, or the court believe there's a high likelihood of reoffending, then bail will be denied.
