"We have, for the first time in a number of years, become a ‘wartime’ Police Department"

Doubling the number of cops responding to even minor 911 calls would effectively cut in half the NYPD’s patrol strength.

The memo also pointed to potential slowdowns in arrest and ticketing activity: “IN ADDITION: Absolutely NO enforcement action in the form of arrests and or summonses is to be taken unless absolutely necessary and an individual MUST be placed under arrest,” the statement said.

“These are precautions that were taken in the 1970s when police officers were ambushed and executed on a regular basis,” the statement added.

“We have, for the first time in a number of years, become a ‘wartime’ Police Department,” the message concluded. “We will act accordingly. FORWARD MESSAGE IN ITS ENTIRETY TO ANY AND ALL [members of the service.]”
