“In Louisiana, we toughened our laws a couple of years ago,” Mr. Jindal said. “If he had been involuntarily committed here, if he had tried to buy that gun here, he wouldn’t have been allowed to do that.”
He added: “Look, every time this happens, it seems like the person has a history of mental illness. We need to make sure the systems we have in place actually work.”
Mr. Jindal said investigators had interviewed Mr. Houser’s family and were examining journals found in his hotel room in which he described his intention to carry out a shooting in the theater. The authorities believe Mr. Houser went to multiple theaters in southern Louisiana before picking the one in Lafayette, the governor said.
