U.S. Attorney General William Barr said the murder rate in Chicago dropped by almost half after the riots that followed the death of African American George Floyd on May 25.

“The results of those actions speak for themselves: over the first five weeks of Operation Legend in Chicago, murders dropped by 50% over the previous five weeks,” Barr reported at a news conference in Chicago on Sept. 9.

He also added, “August ultimately saw a 45% decrease in murders compared to July, and a 35% decrease compared to June.”

Barr gave a reference to the high point of crime in the city, before Operation Legend, when special forces were sent to the city, given the inaction of Democratic Mayor Lori Lightfoot, and Chicago Police Superintendent David Brown.

“When the operation was announced on July 22, homicides in the city were up 51% over 2019. Over the previous weekend, more than 60 people had been shot in Chicago, with over a dozen fatalities,” Barr reported.

The operation was set up by President Trump in July, shortly after LeGend Taliferro, a 4-year-old African American boy, was killed by a stray bullet, in Kansas City, Missouri, while asleep during the riots that occurred in the city, according to Fox News.

“The purpose of the operation was to make clear that his life mattered, his name should be remembered, and other innocent victims like him, including the 8-year-old girl killed in Chicago on Labor Day, should not suffer such senseless death,” Barr explained.

As of July 22, murders had increased 47 percent compared to the same period last year. Three hundred and eighty-five deaths in total, including nine children.

More than 500 arrests were made during operations to protect citizens and federal assets, and more than 124 people were charged with criminal offenses, authorities announced.
