When I think about prosecutor reform, it is usually more like “prosecutors should make clear that they aren’t going to prosecute lesser offenses”. For example, the DA might tell the police department they won’t prosecute anyone brought in for marijuana possession. During the epidemic, the prosecutors might tell police they won’t prosecute minor offenses like traffic violations. These suggestions invite debate over the rule of law versus harm reduction.
Tom_Terrific seems to be more worried about corruption and perverse incentives in the prosecutor’s office. I agree that the prosecutor-police relationship invites corruption, simply because they depend on each other and share a similar motivation to enforce the law. I think this is why we elect most (local) prosecutors, as a check on corruption. If the police are out of line and the prosecutor is abetting their crimes, then in theory the people would vote out the head prosecutor (and maybe the police chief, too).
Making the prosecutor an elected official introduces a new and perverse incentive: personal political ambition. One example would be a refusal to back down after seeing exculpatory evidence. If I remember correctly the North Carolina Bar Association cited the prosecutor’s upcoming reelection as a motivating factor in his handling of the Duke Lacrosse cases. But is political ambition generally a motivating factor when prosecutors hesitate to indict police officers?
I have no doubt that more than a few prosecutors consider how indicting a police officer will affect their reelection prospects. But I also think there are at least two other major factors: an existing bias towards the police officer (based on the prosecutor’s personal relationship with the police) and issues of resource allocation for prosecuting cases. In list form, I have in mind three factors or biases:
The prosecutor is biased in favor of the police, due to his or her close working relationship with the police.
The prosecutor is biased for or against the police depending on the local political situation, due to personal political ambition.
The prosecutor is biased against indictment of any weak case due to limited resources.
Having established my own mental model for prosecutorial behavior, what reforms will encourage prosecutors to indict police officers who (in my opinion) should be indicted?
The most obvious reforms do not really count as prosecution reform - things mentioned by Tom_Terrific. For example, new recording technology like body and dashboard cameras serve to strengthen the case against police officers who do wrong. By providing hard evidence of wrongdoing, such technologies work to make a strong case against the police officer, which in turn weakens prosecutor bias no. 3 (biased against indictment of weak cases). Another example is shifting public opinion and with it the local political situation. In theory, if local voters think a particular police officer should be indicted (and that the prosecutor should be held accountable for non-indictment), then a prosecutor facing reelection will take that into consideration under prosecutor bias no. 2 (biased due to personal political ambition).
And so from a theoretical standpoint I think bias no. 1 & 2 cancel out, and we are left with bias 3 which is reasonable in my opinion.
I am curious as to what kind of reforms the OP had in mind. Simply declaring that prosecutors shall indict police officers from now on won’t fly with me - that’s the goal (
