A woman accused of sucker-punching a pro-life activist in a now-viral video street interview has had her case dropped because Manhattan District Attorney Alvin Bragg’s office missed a key filing deadline, according to the victim’s attorneys.

Brianna Rivers, 30, of the Bronx, allegedly punched pro-life activist Savannah Craven Antao while the journalist was interviewing her for the pro-life organization Live Action in New York City in April. 

Rivers was charged with second-degree assault, but prosecutors dismissed the case in July when they failed to turn over evidence on time, according to the Chicago-based Thomas More Society, which plans to file a civil lawsuit against Rivers on behalf of Craven Antao.

The Thomas More Society said that Savannah went to the emergency room for stitches, resulting in $3,000 in medical bills. After the attack, Rivers walked away from the scene of the crime with both middle fingers extended, the public interest law firm said. 

"District Attorney Bragg’s shocking refusal to uphold justice only works to undermine confidence in the system, especially when our political climate has become as fraught as it is now," said Christopher Ferrara, senior counsel at Thomas More Society.

"Failing to prosecute these clear-cut charges sets a dangerous standard for how our society responds to violence against those engaging in democratic dialogue."

A spokesperson for Bragg’s office told the New York Post that it is "taking immediate internal steps in light" of the botched case.

"Every victim deserves their day in court, and our office has reached out to apologize to Ms. Craven Antao for the unacceptable error of missing the discovery deadline," the spokesperson said in a statement.

The Manhattan District Attorney’s Office did not immediately respond to Fox News Digital’s request for comment early Saturday. 

Video taken by Antao’s husband captured the moment when Rivers grew fed up with the conversation she had been having with Antao. 

The assailant stopped mid-speech and delivered two blows straight to Antao’s face. The reporter was sent reeling off camera as the attacker walked away from the scene.

Antao was left cut and bloodied by the altercation.

Rivers, in a Facebook post, accused Antao of inciting the attack by antagonizing her. 

"To Savannah, I sincerely apologize but cannot sit around and allow you to continue pushing this one sided narrative. I understand hands being put on someone is never the answer, but throwing rocks and hiding hands is worse," she wrote, adding, "She knows the truth, and she needs to release the footage in its entirety. Savannah is a professional antagonist, not a ‘reporter’ and the truth will be told."

"Real Time" host Bill Maher asked an internet culture researcher Friday about memes to understand how people get "inspired to kill." 

Memes, or "historical documents" with various interpretations, were engraved on the shell casings of late Turning Point USA founder Charlie Kirk’s suspected assassin, "Real Time" guest Aidan Walker said.

Kirk’s accused killer etched gamer-inspired and antifascist messaging on his casings, including, "Hey, fascist! Catch!" and a reference to a World War II anthem.

"But [memes] take on new meanings, I mean this is part of why people get inspired to kill," Maher said. "Because they get insulted by them, right? They get hurt by them. They have a meaning that a lot of us older people are not getting, correct?" 

The discussion came in the wake of Wednesday’s deadly shooting at a Dallas I.C.E. facility, where one detainee was killed, and two others were wounded before the shooter took his own life. The gunman reportedly left behind a bullet casing inscribed with the phrase "anti-ICE." 

He was almost "murdering ironically," Maher considered.

"I mean, that’s a place society has never been," Maher continued. "Yes, young men are bad and fumbling to get women to agree to what they want to do. But it was never like this. We never had the term incel [involuntarily celibate]." 

A lot of memes can also be ironic, Walker explained.

"In a way it’s a little bit like dog whistle…they’re so layered in, you know, I don’t really mean this, but you can put this sort of anti-social or hateful idea behind that," he described.

The 26-year-old researcher attributed problematic anti-social behavior to not just an affordability crisis but a "crisis of meaning."

"You have a lot of especially young people who don’t see a future for themselves, who feel lonely, who feel alienated," he discussed. "And they congregate in these online spaces sort of outside of the mainstream where they feel like that online world is more important than their real world."

Walker went on to share "the way out" that he says gives him hope.

"It’s giving people those social bonds… giving everybody the shot at dignity and the shot at being seen in our culture," he said. 

While Republicans like Vice President JD Vance blame "left-wing political radicalization" for recent violence, Maher didn’t mince words in his closing monologue for those arguing the Left is "more approving" of it:

"You keep saying the Left is more approving of political violence – well who do you think that’s going to be aimed at?" Maher asked. "I know it feels exhilarating to make the liberals cry their liberal tears after they made you feel disrespected and looked down on flown over and called the nutty ones. But come on, I thought you were the tough guys. Get over it."
