You ascribe authority to the police they do not have. They make apprehensions, the magistrate or arraignment judge decides to hold or release. The DA, States Attorney or Grand Jury indicts on specific charges.
Here in CT we don’t have DAs, our Stated Attorneys are appointed employees not elected politicians and we don’t use a grand jury system to indict. Much smoother, less political system than New York. We also still set cash bail got most who are arrested
