Well, it raises and interesting point: the ability to pay the bail set has very little to do with how dangerous the person is, right? So the wealthier you are, the more dangerous you can be and still win your freedom. It's almost as if bail should be conditioned on how dangerous the person is, not how much money they have.
I'm not at all endorsing paying bail to release dangerous criminals, but these examples of a non-profit putting up relatively small bail amounts to release dangerous people does pretty well highlight the issue: the bail system needs reform to focus on the danger, not the wealth, of the accused.
