Adams' announcement came in the wake of a series of highly publicized, lethal crimes in New York City that have occurred in the weeks since he was sworn in on Jan. 1.

The "Blueprint to End Gun Violence" will within three weeks put more police officers on patrol in 30 precincts where 80% of the city's violence takes place, according to Adams. He said the officers will be identifiable as New York Police Department employees, and will have body-worn cameras and "enhanced" training and oversight.
