The white Texas police officer who slammed a bikini-clad Black teen to the ground at a pool party resigned Tuesday amid social media backlash and calls for his firing.

Cpl. Eric Casebolt was placed under administrative leave and has resigned under investigation, the McKinney Police Department announced during a press conference today.

The incident, called "indefensible" by the city's police chief, sparks questions after police brutality incidents against Black Americans in cities such as Cleveland, Baltimore and Ferguson have swept the nation.

"Our policies, our training, our practice, do not support his actions," McKinney Police Chief Greg Conley said in a press conference. "He came into the call out of control, and as the video shows, was out of control during the incident." 

Here are 10 powerful reactions to the McKinney Police Department's announcement on Twitter: 

Why should we trust authority these days when they are abusing their power. #McKinney Politics resolves nothing.

@blueeyedgagal @PolitiBunny No he resigned because as a cop he knows the severity of drawing a gun on unarmed teens #mckinney

Eric Casebolt resigning is not justice. Eric Casebolt being charged with assault and spending some time in prison would be getting closer.

Because #America is America, the cop who resigned in #McKinney will probably write a book about diversity & be a motivational speaker soon.

Despite some praise for how the McKinney Police Department has reacted to the media since last Friday's pool party incident, outrage and a lingering sense of impropriety still pervades the city and nation. “There is an indication based on watching the video that the white people who were around the officers weren’t talked to, they weren’t pushed away, they weren’t told to get on the ground, they weren’t put in handcuffs, Pete Schulte, an attorney and former McKinney officer and deputy reserve, told Fox4 Dallas.  "The only individuals McKinney police were doing that to were those that were African-American.”
