Along with officially closing the federal investigation of the police shooting of Michael Brown on Wednesday, the U.S. Department of Justice released a report that finds evidence that the Ferguson police department has engaged in discriminatory practices targeting African Americans.

The Justice Department announced that it did not find sufficient evidence to charge former Ferguson Police Officer Darren Wilson in the shooting death Brown last August. The shooting occurred on Aug. 9, 2014 after Wilson stopped the 18-year-old for walking in the street. A confrontation of some sort then ensued before Wilson fatally shot the unarmed African American teen. Although he claimed that Brown charged at him, several witnesses said that Wilson opened fired even while Brown was surrendering with his hands in the air. Nevertheless, a grand injury failed to indict the 28-year-old white cop in November.

"There is no evidence upon which prosecutors can rely to disprove Wilson's stated subjective belief that he feared for his safety," reads the Justice Department report, according to CNN. As a result, federal civil-rights charges will not be filed against the former cop.

"While credible witnesses gave varying accounts of exactly what Brown was doing with his hands as he moved toward Wilson -- ie, balling them, holding them out, or pulling up his pants -- and varying accounts of how he was moving -- i.e. 'charging,' moving in 'slow motion' or 'running' -- they all establish that Brown was moving toward Wilson when Wilson shot him," the report says.

The Justice Department also issued a 100-page citing evidence of systemic racial discrimination by the Ferguson police and court system against the African American community.

According to the DOJ investigation, Ferguson police and courts used minor traffic and other violations to raise money for the city, and disproptionately targeted African Americans for traffic infractions and jay walking.

The report also shows that in 88 percent of the cases where Ferguson police documented the use of force, it was used against an African American, reports USA Today. In addition, in cases in which a canine was used to bite someone, the person bitten was African American 100 percent of the time.

Although African Americans make up 67 percent of the population in Ferguson, they accounted for 85 percent of the drivers stopped by police, 90 percent of the people issued tickets and 93 percent of the people arrested within a three year time span.

To address what the DOJ describes as a "pattern and practice" of discrimination against people of color, the department released 26 recommendations that include police training to curb bias policing, the implementation of community policing and refocusing police stops, searches and ticketing to protect the public rather balance the city budget.

Furthermore, investigators recovered mutliple racially charged e-mails that were exchanged between employees of the police department and the Ferguson Municipal Court.

"Our review of documents revealed many additional email communications that exhibited racial or ethnic bias, as well as other forms of bias. Our investigation has not revealed any indication that any officer or court clerk engaged in these communications was ever disciplined," the report says.

One email suggested that President Obama would not be re-elected, saying "what black man holds a steady job for four years.''

Another email sent in April 2011 email depicted President Obama as a chimpanzee, while an email dating to June 2011 described a man seeking to obtain "welfare" for his dogs because they are "mixed in color, unemployed, last, can't speak English and have no frigging clue who their Daddies are."

An October 2011 email included a photo of a bare-chested group of African women along with the caption: "Michelle Obama's High School Reunion."

During a news conference on Wednesday, Attorney General Eric Holder addressed the new DOJ report.

"It's not difficult to imagine how a single tragic incident set off the city of Ferguson like a powder keg," Holder said, reports ABC affliated KSPR. He pointed to the use of excessive force overwhelmingly against African-American residents and the mistreatment of people of color.
