I think it is a hard sell. It is counterintuitive, but the evidence is sufficiently clear that, if you are placed in pretrial detention, the likelihood that you're going to be exposed to criminality, lose confidence in yourself and have sufficient social barriers placed in front of you because of that predisposes you to be more inclined to be engaged in criminality than before.
If you can keep people out of pretrial detention, you're going to reduce potential criminality. It's actually a benefit to public safety in the long run.
