so usually its after a new crime is commited, the police stories read like:
"X suspected of serious crime violated his electoronic home monitoring Y amount of times, we rearrested him during the act of a seperate crime"
if both options arent funded/run appropriatly public safety is harmed either way
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.
"Bond reform so no one stays in jail"
if every american suspected of shooting someone is held in jail rather than released, we have just removed the most likely population of people who cause future shootings. from the safety of the publics perspective, now the surviving victims/witnesses are more likely to be victims of more crimes because the suspected violent attackers are back on the street.
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. how much is a good question tho.
