The apparent terror attack in San Bernardino, California, is raising fears in other mid-sized cities around the United States.

In suburban Birmingham, Alabama, Anita Jefferson says she didn't consider her hometown much of a possible target before the mass killing in San Bernardino. Now, she finds herself worried about the possibility of an attack at a location like the suburban shopping mall where she works.

And Tim Harrington of Jacksonville, Florida, says he doesn't feel as safe as he once did. He made his comments while touring a museum in Louisville, Kentucky.

Psychology professor Marjorie Sanfilippo doesn't believe people will change their behavior because of the San Bernardino shootings. But she says that could change if there are more random attacks in public places.
