Organizers of the Dallas Against White Supremacy rally say they're disappointed with the way the rally ended.
Dallas Police tell us five people were detained during the protest, and later released without charges.
That's a small number compared to the thousands who attended the rally.
But the rally was not the issue last night.
It was the impromptu aggressive protest that started after the rally, across the street.
About 300 protesters participated, at its peak, attacking each other and police.
The energy of the protest, at first, was light hearted, with people from all walks of life coming together.
Among the people were those representing the anti-fascist movement, or antifa.
Organizer Eric Ramsey had been working with Dallas Police and had identified the group as one of several that could cause tension.
"I was aware that antifa were on their way here." said Ramsey, "and I was also aware that they had been turned away from our rally because they were carrying weaponry."
Ramsey said his own volunteers turned them away, but as night fell and the rally wrapped up, those protesters started marching, yelling obscenities at police.
They marched to Pioneer Park Cemetery, where they were met by state police and Dallas Police, in riot gear, guarding a Confederate monument.
That's where things turned physical among protesters with some throwing water bottles and threatening to open fire on officers.
Peaceful protesters, who were at the rally, stood by in disgust at the violence.
Ramsey says Dallas Police made sure everything went smoothly, even as the situation escalated.
Dallas Police have not said anything further about the rally or protest, referring us only to the department's tweets.
