"There are several photos of heterosexual couples kissing in the yearbook..."

But a photo of a gay couple kissing was blacked out because it was deemed 'provocative' and 'illicit'. 

From NJ.com:

Andre Jackson said he never thought he would offend anyone when he bought a page in the yearbook and filled it with several photographs, including one of him kissing his boyfriend.

But Newark Superintendent of Schools Marion Bolden called the photograph "illicit" and ordered it blacked out of the $85 yearbook before it was distributed to students at a banquet for graduating seniors Thursday.

"It looked provocative," she said. "If it was either heterosexual or gay, it should have been blacked out. It's how they posed for the picture."

The Superintendent has since issued a public apology, though she didn't contact Jackson personally, and the district has announced that the school will reissue the yearbook.
