November 2017 - Racial slurs - U.S. Air Force Academy Preparatory School
In late September, five black cadet candidates found racial slurs scrawled on message boards on their doors at the U.S. Air Force Academy Preparatory School. One candidate found the words “go home n‑‑‑‑‑‑” written outside his room, his mother posted on social media, according to the Air Force Times.
But on Tuesday, the school made a jolting announcement. The person responsible for the racist messages, the academy said, was, in fact, one of the cadet candidates who reported being targeted by them.
November 2017 - Racist graffiti - Riley County

Dauntarius Williams, 21, of Manhattan, “was genuinely remorseful and expressed sincere regret” of the negative media attention received as a result of his actions, Riley County Police Department said in a Nov. 6 release. 
August 2012 - Charlie Rogers - Homophobia - Omaha
Three masked men allegedly bound Rogers and carved homophobic slurs into her skin Sunday, Lincoln police said. The incident has been classified as a hate crime because derogatory terms for lesbians were used, said Officer Katie Flood, a spokeswoman for the Lincoln Police Department.
But the Lincoln Police Department said Tuesday that "the physical evidence conflicted with Charlie Rogers' version of events" and that "extensive investigation revealed numerous inconsistencies."
Rogers was arrested Tuesday, police said.
Her attorney, Brett McArthur, told CNN Tuesday night that Rogers had agreed as part of an arrangement to turn herself in, in exchange for a personal recognizance bond.
