An Army psychiatrist at Fort Hood, Texas, murders 13 of his service mates. A Pakistani immigrant tries to set off a car bomb in Times Square. An American convert to Islam murders a military recruiter in Arkansas. Each subscribed to a radical strain of Islam that, they believed, directed them to defend their faith by killing Americans. These attacks, along with the dozens of homegrown plots we know about, raise obvious questions about dangers that may be emanating from the American Muslim community of 2-3 million people.
That suggests that Rep. Peter King, New York Republican, who is chairman of the House Homeland Security Committee, was right to launch hearings on "The Extent of Radicalization in the American Muslim Community and That Communitys Response."
Indeed, despite charges that Mr. King is conducting a "witch hunt" that smacks of the worst of McCarthyism, Congress would be derelict if it did not study such matters.
Homegrown threats against America that are fueled by radical Islam are on the rise. Law enforcement officials arrested 22 violent jihadist suspects from May 2009 to November 2010, compared to 21 in the previous seven years, the Congressional Research Service reported.
Five American Muslims left Northern Virginia to train with radicals in Pakistan in 2009, while 20 young Somali-Americans left Minnesota that year to join the al Shabaab Islamist group in Somalia.
Since Sept. 11, 2001, the nation has endured more than 50 homegrown terrorist plots, involving about 130 people, The Wall Street Journal reported - plots to blow up the Brooklyn Bridge, an office building in Dallas, a federal courthouse in Illinois, Washington's Metro mass transit system and the trans-Alaska pipeline. Just this month, a Colorado woman who converted to Islam pleaded guilty in federal court to conspiring to provide material support to terrorists.
While Mr. King has taken the heat, top administration officials share his concerns. Homeland Security Secretary Janet Napolitano told Congress last month that plots to attack America increasingly come from U.S. citizens and residents "inspired by al Qaeda ideology," while Attorney General Eric H. Holder Jr. said he increasingly worries about "people in the United States, American citizens."
American Muslims also are concerned. Some 61 percent of them said they were very or somewhat concerned about the potential rise of radical Islam in the United States, according to a 2007 Pew Research Center poll.
They may have good reason. Eight percent of American Muslims say they believe that suicide bombings to defend Islam are at least sometimes justified, the poll found, while 5 percent view al Qaeda favorably - with another 27 percent saying they didn't know or refusing to answer.
The concerned Muslim Americans include Zuhdi Jasser, who founded the American Islamic Forum for Democracy after Sept. 11 out of concerns that Muslim American leaders were not speaking forcefully enough against radical Islam and the violence it breeds; Zainab Al-Suwaij, who founded the American Islamic Congress after Sept. 11 to, among other things, "champion pluralism and condemn all forms of intolerance," and Hedieh Mirahmadi, who founded the World Organization for Resource Development and Education to strengthen the influence of moderate Muslim thought.
Interestingly, we heard no charges of a "witch hunt" when Sen. Joseph Lieberman, Connecticut Independent, held 14 hearings about homegrown terrorism from 2006 to 2009 as chairman of the Senate Homeland Security Committee. Nor did we hear them when Rep. Jane Harman, California Democrat, held several hearings while chairing a House Intelligence subcommittee.
Mr. King's hearings, by contrast, have attracted criticism due as much to his blunt language as anything else. But controversy about Mr. King should not deter us from the vital job of understanding the homegrown threat that America may face.
If lawmakers ruffle some feathers in their quest to protect the nation, so be it. The issue is too important to avoid.
