Dallas police arrested Dominique Alexander, the leader of the activist group behind the Dallas Black Lives Matter (BLM) July 7 protest that ended in the horrific ambush of five officers dead and nine others wounded. He was taken into custody Wednesday for 10 outstanding warrants in two counties.

The same day of his arrest, Alexander sparred with Dallas Mayor Mike Rawlings at a city council meeting and, later, with Police Chief David Brown by email over yet another BLM protest his group planned for Wednesday evening.

Although leftist reverend Jeff Hood eclipsed Alexander in the media spotlight of the Dallas police shootings, Alexander, 27, is the founder of the Next Generation Action Network, a social justice warrior group that organized the Dallas BLM march where gunman Micah X. Johnson opened fire killing five officers and wounding nine others at the demonstration’s end.

Wednesday, Alexander was arrested on class B misdemeanors and outstanding warrants — nine alias warrants out of the Dallas Police Department, totaling $5,004.32 and one hold for the Collin County Sheriff’s Office in the amount of $367, NBC DFW reported. Alexander was booked at the Lew Sterrett Justice Center at the Dallas County Jail.

Earlier in the day, Alexander was removed from a Dallas City Council meeting after a confrontation with Mayor Mike Rawlings, which the community organizer and minister posted to his Facebook page. Alexander was issued a criminal trespassing warning, Dallas’ WFAA 8 reported.

On Tuesday, Alexander requested a one-on-one meeting with Dallas Police Chief David Brown. Then on Wednesday, Brown posted the email exchange with Alexander on his blog. In it, the Police Chief asked Alexander to cancel Wednesday night’s downtown protest. Brown wrote: “What’s more important than our officers safety…cancel it and don’t schedule anymore in the downtown area…I insist.”

Brown wrote: “I will meet with you on the condition you publicly agree to discontinue protests in the downtown area given the tragic circumstances of July 7 and the associated concerns of our officer’s safety…and that you choose a protest location more tactically advantageous to offer safety.”

The Next Generation Action Network leader responded he could not cancel Wednesday night’s rally but would lose the march. He’d already organized a second and smaller July 29 BLM Dallas protest, weeks after the shootings, arguing that enough time passed to get back on message, Breitbart Texas reported.

Alexander has a history of getting into trouble with the law. The Dallas Morning News reported some of his past charges include theft, forging a check, evading arrest, and injury to a child causing serious bodily injury, according to Dallas County records. In 2015, the Dallas newspaper reported on Alexander’s troubled history.

One year ago, Alexander and his activist organization weaved themselves into the fabric of the McKinney “pool party.” At one of the press conferences, Alexander addressed particulars of the incident in broad brushstrokes based on a seven minute social media video, debating when pushed for the facts.

Breitbart Texas reported:

“Weaved through the community’s commitment to solidarity, was the pervasive punting of the facts. Things like when pushed for a response if the kids were rightfully at the pool, Alexander deflected and said, ‘in order to be able to answer that question, I would have had to have been at that party.’ ‘And just like city officials we’re going to wait for all of those facts to come out…’”

The small “rally” went on Wednesday night without Alexander, who remained in jail. No bond was set Wednesday, nor at the time of filing this report.
