Investigation:
> civilian investigators don’t have direct access to the [body cam] footage. They email requests to the NYPD, which decides which footage is relevant. The department takes its time.
Adjudication:
> [E]ven if the CCRB substantiates a case, the commissioner still has complete authority over what to do next. He can decide to simply ignore the recommended punishment. The commissioner can also let the case go before an internal NYPD judge (whose boss is the commissioner). If the judge decides punishment is merited, the commissioner can overturn or downgrade that, too.
Punishment:
>In 2018, the CCRB looked into about 3,000 allegations of misuse of force. It was able to substantiate 73 of those allegations. The biggest punishment? Nine officers who lost vacation days, according to CCRB records.
