Last month, a student at Ohio State Universityran into people with a car and stabbed them with a knife.The victims survived, but police shot and killed the attacker,Abdul Razak Ali Artan, at the place the incident happened.Since then, members of the Muslim communityhave been trying to understand what made Artan carry out such violence.Artan was a Somali refugee who came to the U.S. with his family in 2014.He had been a successful student.He earned honors at a local community college before going to Ohio State,one of America's largest universities.Officials at the mosque near the family's home say Artan was not well-known to them.They add that they are concerned that others may judge the entire communityby the actions of one young man.Robert Fitrakis is a lawyer representing Artan's family.He describes how the family fears the political climate in the United States."I'm not sure they want their face on camera," he says.Mohamud Mohamed Ahmed is a member of the Muslim communityat Abubakar Assiddiq mosque in Columbus."I've been in this country 25 years, so we are Americans,but we are Muslim, too.We should not be viewed as people who came from another planet.We are not aliens. We are citizens of this country."The issue of refugees and migrationhas become an important political issue in the United States.Supporters of strict immigration policy say the attack showsthe danger that immigrants, or refugees, could present.Earlier this month, for example,President-elect Trump said the attack at Ohio State Universitywas "yet one more tragic reminder that immigration security is now national security."However, refugee resettlement supporterspoint to the need to help people from conflict areas around the world.Becca Heller is the director of the International Refugee Assistance Project.She criticized the words used by Trump in an interview with NPR news."That rhetoric has had an impact.Trump has been successful in politicizing refugee admissionsin a way that they have not been politicized before."The number of refugees admitted to the United States has increased since 2002.However, the number of refugees admitted to the U.S reached"historically low levels" in the year following the September 11 attacks in 2001.A report by Congressional Research Services, or CRS,says that 27,131 refugees were allowed into the country in that year.The number of refugees admitted in 2017 could reach 110,000, the CRS report says.Any possible changes to immigration and refugee policyremain unclear as the Trump administration begins on January 20.
