The painting Officer Dave Hamblin found offensive (Facebook)

A police officer father in the United States has taken to social media to complain about a piece of artwork displayed at his daughter’s school.

Kentucky cop Dave Hamblin is outraged by the painting which depicts two black people with a gun pointed at their head.

On one half of the painting, under the title “1930″, a Ku Klux Klan member is pointing the gun.

On the other half, titled “2015″, a white police officer is shown pointing the gun at what looks like a African American child.

The painting was from a school project inspired by racial violence depicted in Harper Lee’s book, To Kill A Mockingbird.

Police officer Dave Hamblin, who goes by the name Dave Kingmen on Facebook, says the picture is upsetting and creates “future cop haters”.

“We speak of tolerance, we speak of changing hostile environments, we speak of prejudice, and we speak of racial relations, yet, when it comes to hostility toward police, their families, and profiling them through bigotry we are expected to tolerate it,” “Kingmen” wrote.. “I will not, nor will my child.”

The cop has asked for the picture to be removed but the school has seemingly turned down his request.

“When discussing social injustice, people will likely be offended by some topic,” said Tracy Green, a school spokesperson.

“The drawing is a student’s artistic representation based on the lens through which the student viewed that issue and the student has a First Amendment right to share that opinion.”
