The Dallas Police Department plans to make changes to its off-duty work rules after discovering that a police impersonator with a criminal past used an off-duty job system to place real officers in security roles. The impersonator, Diamon Robinson, who went by the alias Mike King, had a long history of crimes like stealing cars and forging checks, but was still able to build trust and respect in the community and even work as a bodyguard for a congresswoman before being shot and killed by SWAT officers last week.

Why it matters

This case highlights significant security and vetting issues within the Dallas Police Department's off-duty work program, which allowed a dangerous criminal to infiltrate the system and gain access to real officers and sensitive information. It raises concerns about public safety and the integrity of law enforcement.

The details

Authorities discovered that Robinson had two accounts on the off-duty job-sharing platform RollKall - one as an officer and one as an external coordinator. He used these accounts to promote his own security business called Off Duty Police Services and place real officers in security roles, despite his criminal history. Police are still investigating how Robinson obtained fake federal agent uniforms, ID badges, and government license plates that allowed him to continue his impersonation.

  • Last week, Robinson was shot and killed by SWAT officers after pulling a gun on them during an attempted arrest.
  • Over an 8-year period, Robinson had a criminal record that included stealing cars, forging checks, and running scams.

What they’re saying

“We are going through, obviously, our checkpoints, our audits and things like that because there's always room for improvement. And so we are working with RollKall very closely. Obviously, this platform was fully vetted. We believe in the program. And so moving forward, we are going to put additional safeguards in place that will be forthcoming in the next couple of weeks.”
