The story of Chicago students showing their classmates pictures of ovens and telling them to “get in” is beyond sickening.

Nowhere to be found.

Sadly, many of the Twitter responses to the story illustrate the problem.

Editor’s note: This post has been corrected to reflect that it was the students — not their principal — who showed their classmates pictures of ovens. We apologize for the error.
