The performer whose views had shifted — Caleb Keeter of the Josh Abbott Band, which was part of the weekend lineup in Las Vegas — said on Twitter on Monday that he had been “a proponent of the Second Amendment my entire life.”
He added, “Until the events of last night. I cannot express how wrong I was…”
Mr. Keeter, a guitarist, said that members of the band legally had firearms on the bus, but refrained from using them for fear the police would mistakenly think they were part of the attack.
“We need gun control RIGHT. NOW.” Mr. Keeter wrote. “My biggest regret is that I stubbornly didn’t realize it until my brothers on the road and myself were threatened by it.”
Mr. Keeter said he had written a living will and goodbye messages to his parents and partner on Sunday for fear that he would not survive the night. Members of his crew received shrapnel wounds, he said.
