An internal investigation was launched after a St. Louis police officer decided to comment in a Facebook post using a meme comparing the infamous white supremacist organization, the Ku Klux Klan, to Black Lives Matter activists over the weekend.

Protester Lisa Clancy shared her experience attending one of many protests in St. Louis in wake of the controversial acquittal of former officer Jason Stockley.

In 2011, Stockley was recorded while in pursuit of Smith stating that he intended to kill him. Smith was shot five times after a high-speed chase and crash after officers tried to apprehend him for a suspected drug deal at a Church's Chicken restaurant.

Blavity reported that the former officer allegedly planted a gun on the victim to cover up wrongdoing. Stockley was found not guilty of first-degree murder and armed criminal action charges by presiding St. Louis Circuit Judge Timothy Wilson on Sept. 15.

In an interview with Newsweek, Clancy said that a user named Deron Riley commented on her post even though she wasn't friends with the man on the platform. After a quick Google search, she found out that Riley was a police officer with St. Louis Metropolitan Police Department.

"Since Ferguson, there's been this conversation about the trust and relationship-building that needs to happen between community and law enforcement, and letting this kind of behavior go on totally undermines everything they need to be working on right now," she told the outlet.

On Sunday, Sept. 17, Clancy posted screenshots of her interaction with Riley on Twitter in an effort to bring the matter to the police department and Mayor Lyda Krewson. 

Clancy's actions were successful and on Monday, a spokesperson for the St. Louis Metropolitan Police Department told the Belleville News-Democrat that the department had launched an internal investigation into “the matter,” but they did not confirm if the person was indeed one of its officers.

However, she isn't confident the department will reprimand Riley.

"The fact that they've been silent shows me that, one, that kind of behavior is OK, and two, there's some deeply embedded racism in that institution."
