ROSEBURG, Ore. — A week has passed since J. J. Vicari huddled underneath a desk while gunshots exploded in the classroom next door. Now he is thinking about guns. Not about tightening gun laws, as President Obama urged after nine people were killed at the community college here. But about buying one for himself.

“It’s opened my eyes,” said Mr. Vicari, 19. “I want to have a gun in the house to protect myself, to protect the people I’m with. I’m sure I’ll have a normal life and never have to go through anything like this, but I want to be sure.”

Mr. Obama plans to visit Roseburg on Friday to meet the grieving families of yet another gun rampage, but many people here are bristling at his renewed call for stricter gun laws. In some ways, the rampage at the college by a 26-year-old student, Christopher Harper-Mercer, has actually tightened the embrace of guns in a rural town where shots at rifle ranges echo off the hills and hunters shoot deer and elk through the fall.
