Kawaski Trawick was shot and killed in his Bronx apartment by a New York Police Department officer on April 14, 2019. The NYPD said Trawick had charged at officers with a knife. Video of the shooting shows the officers had escalated the situation — and that one officer then shot Trawick over his more-experienced partner’s objections.

While the NYPD has never released video of the shooting, the Bronx District Attorney’s Office released footage of it last month, along with a detailed report. ProPublica separately obtained parts of the videos.

Our analysis of the footage found:

• The officers failed to use techniques from NYPD’s crisis intervention training program to de-escalate the confrontation with Trawick.

• The more-experienced officer, Herbert Davis, who is Black, repeatedly told his partner, Brendan Thompson, who is white, not to use force against Trawick.

• Thompson nonetheless opened fire on Trawick, first with a Taser and then with a gun, killing Trawick.

The NYPD has declined to answer our questions about what happened, citing its investigation, which is pending review by top officers.
