The Memphis Police Department has 35 specialized units. Here's what they do.

In the days that followed the beating and death of Tyre Nichols in early January, and the later revelation that the officers directly involved were part of one of the Memphis Police Department's specialized units, activists began calling for those specialized units to be shut down.

The SCORPION unit, which stands for Street Crimes Operation to Restore Peace in Our Neighborhoods, was disbanded during peaceful protests, sparking celebration among activists. But calls for further shutdowns continued, even as MPD and the City of Memphis invited the Department of Justice to investigate how its specialized units function.

On March 8, the DOJ announced its intent to conduct that investigation, which is a step below a full-fledged pattern or practice investigation, and create a best practices guide for specialized units for departments across the country.

But what exactly fell under the umbrella of "specialized units" was not completely clear until Memphis Police Chief Cerelyn "C.J." Davis and Deputy Chiefs Don Crowe, Stephen Chandler and Paul Wright presented a breakdown of the department's specialized units to the Memphis City Council's Public Safety Committee on Tuesday.

Signs in support of Tyre Nichols are seen in front of Memphis City Hall while Tyre Nichols’ family reviews footage inside of the traffic stop that resulted in Nichols being taken to the hospital in critical condition in Memphis, Tenn., on Monday, January 23, 2023. Nichols was a skater and members of the Memphis skateboarding community came out to support his family.
