What should be done with the mural?
The mural is racist. It contains demeaning images of minorities and has no place in today's courtrooms. It should be painted over. Imagine if you were a black man being sentenced in that courtroom how you would feel.
The mural is historical. It was made in the 30s and it simply depicts the times. Don't take it down. It is a beautiful mural and makes the central courtroom what it is.
The mural has demeaning images and can be viewed as racist, but it is also historical. It is not an image of racism like the Confederate flag, so it should not be painted over.
