Never in my entire career in Washington have I encountered the hype and scare tactics of those opposing the hearings into Islamic radicalization by Rep. Pete King. A classic example was a headline on MSNBC.com: "Inquiry by congressional committee looks like inquisition to many Muslims."

The line of attack is now familiar: If King (R-L.I.) were truly interested in violent extremism, his hearings would focus on a wide range of groups that wreak havoc on America, including neo-Nazis and others; by focusing solely on Muslim extremism, the argument goes, he is betraying his bias.

This is utterly ridiculous. Our organization, the Investigative Project on Terrorism, recently did an analysis of all terrorism convictions based on statistics released by the Justice Department. These stats show that more than 80% of all convictions tied to international terrorist groups and homegrown terrorism since 9/11 involve defendants driven by a radical Islamist agenda. Though Muslims represent less than 1% of the American population, they constitute defendants in 186 of the 228 cases the Justice Department lists.
