The Dallas Police Department has updated its policies on off-duty work following a fatal shooting earlier this year that raised concerns about how officers are hired for outside jobs. The changes stem from the shooting death of Diamon-Maziarre Robinson, who may have used the online platform RollKall to hire off-duty officers while posing as a federal agent. DPD has now prohibited officers from accepting off-duty jobs on RollKall if the job was created by an outside entity or agency.

Why it matters

The incident highlighted potential security risks with the use of third-party platforms to manage off-duty police assignments, as well as the need for stronger vetting and oversight of who can access these systems. The updated policies aim to ensure officers follow department guidelines while still maintaining access to off-duty work opportunities.

The details

According to investigators, Robinson, who also used the name Mike King, may have used the online platform RollKall to hire off-duty officers. Body-worn camera footage showed Robinson sitting in a vehicle as officers ordered him to exit. As he got out of the car, he appeared to reach toward his waist and point what appeared to be a firearm before the video froze and gunshots rang out. Police said Robinson had two active theft warrants and was using a false identity to impersonate a federal agent. Following the shooting, Police Chief Daniel Comeaux issued a memo outlining changes to how the department uses the platform, including prohibiting officers from accepting off-duty jobs on RollKall if the job was created by an outside entity or agency.

  • The shooting incident occurred in early March 2026.
  • DPD has used the RollKall platform since November 2024.
  • Robinson, posing as Mike King, began using the RollKall system in April 2025.

What they’re saying

“On RollKall, there was a feature that allowed outside entities to go on RollKall and place jobs for hire for off-duty officers. That feature has since been turned off. So now, the special employment team personnel is the only working group that can add part-time jobs on the platform.”

— Monique Alex, Executive Assistant Chief, Dallas Police Department

What’s next

The Dallas Police Department said it will continue using RollKall while evaluating additional safety measures to ensure officers follow department policy while maintaining access to off-duty work opportunities.

The takeaway

This incident highlights the need for law enforcement agencies to carefully vet and monitor the use of third-party platforms for managing off-duty police assignments, as well as the importance of robust identity verification and access controls to prevent unauthorized individuals from exploiting these systems.
