ANAHEIM HILLS (CBSLA.com) — A high school principal has apologized for forcing a 16-year-old student to remove her National Rifle Association shirt last month.

Haley Bullwinkle, a sophomore at Canyon High School, said she was asked to change or face suspension because her T-shirt, which featured a buck, an American flag, and a hunter’s silhouette, violated the school’s dress code and promoted gun violence.

Bullwinkle’s father, Jed, emailed the school’s principal, Kimberly Fricker, about the situation.

Fricker responded saying that the gun on the shirt wasn’t allowed.

The principal, however, had a change of heart on Thursday. Bullwinke’s mother, Stephanie, said Fricker called her and said the teen can wear her shirt.

“She was very, very apologetic. She said they’re definitely going to be talking to the staff, training their staff on what is appropriate conduct and what is not. And that (Haley) can wear the shirt, so very happy. It was nice to hear from her,” said Stephanie.

“I feel a bit proud, actually, that I stood up for my rights, and I feel very happy at the outcome,” Bullwinkle said.
