"Did he say anything to make it clear that it was raise your hand in this way as in this Nazi symbol?" Diaz asked.
"He did not say raise your hand in a Nazi symbol way. And I'm pretty sure my classmates just interpreted as raise your hand, let's do this as a joke," Blue said, adding that he thinks the others knew what the symbol represented.

The photo surfaced in a now-deleted tweet on Sunday with the caption: "We even got the black kid to throw it up." At least one student is seen making the OK gesture, which some associate with white supremacists.
The photographer, Peter Gust, defended the students in an interview with a local TV station, saying the gestures are being taken out of context.
"I said, 'OK boys, you're going to say goodbye to your parents. So wave,'" Gust said. "For society to now turn it around and now blame these kids is absolutely wrong."

Asked whether the students are regretful, Blue said, "I think so."
"Some of these people have bright futures ahead of them. ... So why did they do it?" Blue said.
Blue said at least one parent yelled for the students to stop while the photo was being taken. The Baraboo school district condemned the gestures and said it's investigating.
