The St. Louis husband and wife who pointed guns at a crowd marching through a private neighborhood in June are facing charges, Circuit Attorney Kimberly Gardner announced Monday.

Gardner, who was elected in 2016 on a platform of reforming the criminal justice system, reportedly was backed by liberal billionaire George Soros.

In a statement last month, Gardner described the encounter between married lawyers Mark and Patricia McCloskey and the crowd as “a violent assault” against those exercising their First Amendment rights.

“I am alarmed at the events that occurred over the weekend, where peaceful protesters were met by guns and a violent assault,” Gardner said. “We must protect the right to peacefully protest, and any attempt to chill it through intimidation or threat of deadly force will not be tolerated.”

"It is illegal to wave weapons in a threatening manner -- that is unlawful in the city of St. Louis," she added on July 20, announcing the charges of felony unlawful use of a weapon.

Albert Watkins, the McCloskeys' attorney, told Fox News that under Missouri's Castle Doctrine, a person has “the absolute unmitigated right to protect his or her castle or family while on their property.” He said the protesters were trespassing, "damaging and destroying private property and acting in a threatening and hostile fashion."

“If Kimberly Gardner wants to press charges against two attorneys who are protecting their home and their family and themselves on their own property, I will tell you that it will be nothing short of the proverbial clusterf--- with the ensuing assertions that she's doing this for political purposes,” Watkins said.

"And I will tell you that as a person, I don't believe that to be what she is doing,” Watkins added. “I just believe she probably has a difficult time reading the English language.”

George Soros connection

Gardner, a Democrat, was elected circuit attorney of St. Louis in 2016, running on a campaign that promised to reform and rebuild trust in the criminal justice system and reduce violent crime.

She was criticized ahead of the election for releasing a political ad paid for by the Safety and Justice Super PAC that was at least partially funded by liberal billionaire George Soros, the St. Louis Post-Dispatch reported.

The total funds donated by the super PAC were at least $190,750, according to the report, with Soros giving at least $30,000. It was not immediately clear what her campaign budget was or who else contributed.

Gardner at the time told the paper that she had no regrets about accepting help from the super PAC.

Soros is known for backing left-wing causes across the globe, having last year used his super PAC to successfully boost two liberal prosecutor candidates in Virginia over incumbent Democrats.

Beef with Missouri AG

Gardner publicly butted heads with Missouri’s Republican Attorney General Eric Schmitt, who she referred to as a “Trump wannabe” during an online meeting of local political candidates earlier this month, FOX2 St. Louis reported.

Schmitt had earlier criticized Gardner on Twitter for allowing the release of all 36 rioters and looters arrested in the city following protests over the deaths of George Floyd and Breonna Taylor.

“In a stunning development, our office has learned that every single one of the St. Louis looters and rioters arrested were released back onto the streets by local prosecutor Kim Gardner,” Schmitt tweeted June 3.

Gardner responded that only eight of the 36 cases were referred to her office and that police did not provide “admissible evidence."

“He just wants to launch a politically motivated attack against me, even if it means misleading and lying to the public,” Gardner said of Schmitt. “While the AG continues to fuel the division in the community at a time of great pain, suffering and racial divide, my response to the AG: I got work to do."

Lawsuits against Gardner's office

Gardner was sued last week for at least the third time over the state’s Sunshine Law, an open records law that requires the government to respond within three days to requests for public records, the Post-Dispatch reported.

The latest lawsuit claims Gardner’s office failed to fulfill an April 23 open records request for data on case statistics, dismissal data and staffing totals, the paper said. Her office responded in a letter May 12, according to the paper, saying more time was needed to fulfill the request due to the coronavirus.

The Post-Dispatch also sued Gardner’s office in 2019 over her office’s refusal to release copies of contracts with vendors. A judge ruled in the paper’s favor in April, but the paper said Gardner’s office has not yet fully complied.

Gardner sues city officials

Gardner also filed her own lawsuit against city officials in January under a federal law passed to curb the violence of the Ku Klux Klan following the Civil War.

In the suit, Gardner accused city officials, the local police union and a special prosecutor of a “racially motivated conspiracy to deny the civil rights of racial minorities” by obstructing her work to get tough on police misconduct and create change in the criminal justice system, The New York Times reported at the time.

Her opponents denied the accusations, with a police union leader calling the suit “frivolous, desperate and pathetic,” the paper reported.

Gardner has been at odds with the St. Louis police and local legal establishment since taking office and taking steps to hold police officers more accountable, according to the paper.

Conviction rate falls

The rate of convictions under Gardner has fallen dramatically in the past two years, according to a KMOV-TV report from February.

The station obtained data from Gardner’s office that showed prosecutors got guilty verdicts in 51 percent of cases in 2018, and in 54 percent of cases in 2019. The station reported convictions had dropped by about 20 percent.

A spokesperson for Gardner’s office responded to the station at the time, saying that counting plea agreements, the overall conviction rate is 95 percent. They said over 90 percent of cases are resolved outside the courtroom.

“The Circuit Attorney ran on a platform to reduce the number of cases unnecessarily charged in order to focus on the more difficult cases for trial,” the statement said.
