ALBUQUERQUE |  Two Native American brothers were pulled from a Colorado State University tour and now their attorney is asking the school for policy changes.

Campus officers violated the teens’ constitutional rights when they questioned and patted them down without any suspicion of a crime, according to a letter sent Wednesday from an American Civil Liberties Union attorney.

The letter directs the university to reconsider its campus police policies and training to avoid a situation like the encounter with the two Native American brothers

Video captured campus police stopping Thomas Kanewakeron Gray and Lloyd Skanahwati Gray and checking their pockets.

Police said a mother on the tour had called 911, saying she was worried because the Grays were “real quiet.”

A university spokesman didn’t immediately return a message seeking comment.
