Cash bail is so totally counter to the concept of bail, which itself is intrinsic to the idea that we're innocent until proven guilty.
If there are genuine concerns that someone is a flight risk, or that they'll intimidate witnesses, then the police & prosecutors should have to furnish hard evidence of that to persuade the court, and the resulting bail conditions should be as minimal as possible to achieve the effect.
Here's hoping the rest of the US comes to follow Illinois in undoing this abusive practice.
