>i dont really think there is room for debate on the "truthyness" of his statement, as if we kept more people in jail, less people would be out in public able to commit crime.

Your assumption is contingent on the accuracy of the accusations to begin with, and doesn't account for deadweight loss, so this isn't straightforward. This deadweight loss also isn't going to be shouldered by just anybody, but especially the justice system itself. Especially considering the alternative being proposed here is not "total unconditional freedom" but "freedom unless imprisoned for violating bail conditions, and $$$ for the justice system if such a violation occurs". You can make bail conditions quite onerous if you want to but still cheaper than jail cells.

If on account of not making bail we have to put somebody in prison, police may be directed to make less arrests, DAs may be motivated to bring forward less charges, Judges may be inclined to give people lighter sentences, and parole boards may be motivated to release people earlier, as this will free up the limited resource of jail cells.
