Arrests dropped off even more precipitously last week, when cops made 1,481 busts — down 68% from the same period in 2019.

Sixty people were shot last week, police data show — an increase of 253% over the 17 shooting victims reported in the same week in 2019.

But cops made just 21 arrests in gun cases — down 72% from the 74 arrests reported in the same week of 2019.
