The idea that #EmilBove is expanding his theory of “prosecutorial discretion” to a police commissioner under investigation is remarkable for several reasons: 1, it’s novelty; 2, because it appears as if he is expanding the #immunity that #SCOTUS recently granted to presidents to all manner of officials, including the men & women who head the city’s PD; & 3, two of the mayor’s former police commissioners remain the focus of inquiries by the same prosecutor’s office that charged the mayor.
