Teton High School is reconsidering allowing student Halloween costumes, after one student showed up for school dressed as Adolf Hitler.

A second student was dressed as a Jewish person, and the student dressed as Hitler pulled the classmate around with a leash or rope, Jeannette Boner of the Teton Valley News reported this week.

The students put on the costumes during Thursday’s lunch break, and English teacher Marilyn Reiley stopped them as they entered her class, Boner reported.

“There is no simple fix to this,” Principal Sam Zogg told Boner. “We are trying to address this as a staff. These were two kids and not the whole student body. We have to look at the whole issue to prevent even two kids from doing this again.”

Other costumes were problematic as well, Zogg told Boner. One student dressed as a prostitute, another dressed as Jesus, and others wore masks that made them unrecognizable.
