The language got so angry that on Tuesday, the mayor and other city officials put out a statement saying they welcomed Mr. Obama and “will extend him every courtesy.”
And while the mass shooting here has pushed some people toward wanting to arm themselves, it has also pushed others in the opposite direction. Students like Devon Paasch, 36, whose writing teacher, Lawrence Levine, was among the victims, said the killings had intensified her belief that the country needed stricter gun laws. Ms. Paasch was not on campus that morning because she slept through her alarm; she has spent the past week tilting among grief, guilt and a fear of returning to school.
“No kind of gun control is going to stop everything,” Ms. Paasch said. “But in a situation like this, it could have saved 10 lives.”
The debate has rolled across a conservative, timber-producing region where flags are at half-staff and roadside signs solicit prayers for the victims. From a wooded gun range south of town, to City Hall, to KC’s Exchange, where Carolyn Kellim sells handguns and ammunition out of her home, people insisted that the actions of Mr. Harper-Mercer, who was armed with six guns and spare ammunition magazines, would not displace guns from their place in local life.
“That’s why we have guns: We don’t have the government dictating when to get on our knees,” said Ms. Kellim, 86.
After the shooting, gun-control groups and national news media skewered Sheriff John Hanlin of Douglas County, which includes Roseburg, for a letter he wrote to Vice President Joseph R. Biden Jr. after the Sandy Hook Elementary School massacre in Connecticut. In it he said, “Gun control is NOT the answer to preventing heinous crimes like school shootings.” But in church pews and coffee shops, many residents said they still believed he was right. Online, some are using #supportforHanlin to back him.
A community college student has started a petition to allow concealed weapons on all campuses, echoing hotly disputed arguments from national gun groups that mass shootings could be stopped by more “good guys with guns.” In 2011, an Oregon court said public colleges could not ban guns from campus.
Umpqua Community College’s code of conduct banned guns “without written authorization,” and students said some of their classmates were able to carry guns on campus because they had concealed weapons permits. One of them, John Parker Jr., an Air Force veteran, told MSNBC that he was armed when the attack happened but did not intervene. He said SWAT officers might have mistaken him for a killer.
“This just shows you, you have to have a way to protect yourself,” said Makayla Thomas, 19, who raced into a student center when the attack started and huddled there until the police arrived. “It’s happened once. Who knows what can happen?”
Jamie Skinner, 34, a former girlfriend of Chris Mintz, the Army veteran who blocked the door to a classroom at Umpqua Community College and was shot by Mr. Harper-Mercer, said in an interview last week that the massacre in Roseburg would not change her opinion that owning guns was important. Ms. Skinner has worked as an armed security guard, and said she and Mr. Mintz went to shooting ranges for recreation.
“We are a weapons family,” Ms. Skinner said. She and Mr. Mintz have a 6-year-old son, Tyrik, who has autism and who also influenced her attitude toward guns. “I like to have the ability to protect myself and my child,” she said.
But Ashley Schmidt, 28, said the horror she heard through the walls of the classrooms had nudged her toward supporting rules that would regulate guns the way cars are. She was in Classroom 14 in Snyder Hall when the shooting started and ran out amid a storm of gunfire, yelling “Gun! Gun! Gun!” at a girl in the hallway whose earbuds had blocked out the noise.
Ms. Schmidt said she opposed “taking guns away,” and lamented that there was no foolproof way to keep guns away from criminals or would-be mass murderers.
“I’ve always felt like there is nothing I can do,” she said, referring to school shootings. “But I see this country falling apart.”
