Rep. Jasmine Crockett lost her chance at the Senate and her security guard all in a short amount of time. But she lost the first before of an info op by fired CBS late night host Stephen Colbert and lost the second due to the bullets of the Dallas PD SWAT.
A man shot and killed by Dallas police earlier this week was a familiar figure in North Texas law enforcement – and part of the security detail for U.S. Rep. Jasmine Crockett, sources told CBS News Texas.
On Saturday, sources identified the man as 39-year-old Diamon-Mazairre Robinson. He was publicly using the alias “Mike King” and had been using aliases while running a business that placed officers in off‑duty jobs.
Robinson was killed Wednesday night after a standoff with Dallas police SWAT officers. Police said he fled into a hospital parking garage, barricaded himself inside a vehicle, and was forced out by tear gas before pulling a gun on officers.
Sources said he was the subject of a federal investigation, in which he was wanted for impersonating a law enforcement officer.
None of this exactly inspires any confidence in Crockett whose security guy was a convicted criminal operating under an alias.
This is one those ‘what did she know and when did she know it’ questions that no one in authority is going to ask.
CBS News Texas has been researching Robinson’s criminal history, which includes seven arrests for theft in Dallas, Duncanville, Irving, Dallas County and by the Texas Department of Public Safety.
All of the arrests were between 2009 and 2012 and include misdemeanor and felony charges.
It appears his sentences for those convictions, which he pleaded guilty to all, led only to fines no more than $2,500 and sentences of probation from 1 to 5 years, and in one case, 10 years.
Law enforcement sources also said Robinson drove a replica undercover police vehicle and used license plates stolen from cars outside a military recruiting office
His criminal background raises questions about how he managed extra‑duty jobs for police officers and secured a high‑level security role for a sitting member of Congress.
The answer would seem to be that either Rep. Crockett’s office was incompetent or didn’t care and in the process invited in an armed man who died trying to shoot at SWAT team members into what should be secured spaces.
