Don’t cancel that trip to the Sears Tower just yet.

Attacks on major cities such as Chicago in response to the United States bombings of Afghanistan are possible, but security is tight.

“Yes, there is a risk for every major city in the United States,” said Daniel Kempton, chair of the political science department.

Kempton added that with this risk, security measures at possible targets are high and people should not have any extra worries.

Junior accounting and computer science major Lawrence Gregory believes the security measures are good enough to deal with any attacks.

“Definitely there’s a possibility of the same thing happening to the Sears Tower, but with the security measures taken, that risk has been alleviated,” Gregory said.

The attacks on buildings are not the only thing that worries students.

The threat of anthrax being brought into Chicago worries junior psychology major Sarah Dietz in light of the reports from Florida.

“Anything’s possible now,” Dietz said.

The promise of added security kept people in the city.

Christopher Jones, an assistant professor in the political science department, does not suggest changing travel plans.

He says in doing so, the terrorists win by altering the American lifestyle.

The Associated Press reported that tourism in Chicago was strong over the Columbus Day holiday weekend. People used the trains, took flights and went to Chicago landmarks such as the Shedd Aquarium.

“Chicago is a likely target though, because it is a major U.S. city in a densely populated area with the nation’s tallest building and busiest airport,” Jones said.

Junior electrical engineering major Kyle Doty thinks that anything, including a train or a bus, could be targeted.

“I think every major city is a risk,” Doty said.

Because of the increased security precautions since Sunday’s bombing of Afghanistan, those commuting to Chicago are urged not to worry.
