"Sounds like the mayor was getting a bit desperate to hit the magical $1 billion number.
It does seem that way. In fact, the number is such a stretch that New York City Council Speaker Corey Johnson refused to say the city had cut that much. He and other council leaders had agreed during negotiations to set $1 billion in cuts as the goal, but in his Tuesday press conference, Johnson said that he and the council had fallen short. And police reform activists who had pushed for the cuts seemed to be in universal agreement on that point."
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
