Some bail funds literally don't factor in the crime. The theory is that bail is immoral; the type of crime it's for doesn't matter. If the person shouldn't be on the streets, they shouldn't be allowed bail to be on the streets.

Obviously, a lot of judges are currently using bail for exactly this, to keep people off the streets, which is exactly what the bail funds are protesting, and I get why that's bad, but.... it does lead to exactly this.

Others consider it case by case, usually because they don't want to do something like pay someone's bail only to have them commit another violent crime.
