A pair of police sharpshooters stood atop a day care center in the Bronx on Tuesday morning and peered over the terra cotta and marble facade of a converted movie theater next door. The facade’s mechanical clock was stuck at a couple of minutes after 2. On the ledge, a pigeon cleaned its feathers.

Below, the Grand Concourse, normally pulsing with activity, was deserted and silent, except for the rattle of shop grates being pulled open and police trucks idling. It was saving itself for a police officer’s funeral.

Soon the concourse filled for 10 blocks with officers in their finest dress blues — Class A’s.

They had turned out for the funeral of Officer Miosotis Familia, killed for doing little more than what her colleagues did on Tuesday morning: put on a New York Police Department uniform. Not an hour into her overnight shift on July 5, she was filling out paperwork in the front seat of a police truck when a man fired once through the passenger-side window. She was shot in the head and killed.
