Robert Spencer:

Of course, however unpleasant or politically inconvenient a fact it may be, young Muslim Arab males are responsible for the overwhelming majority of terrorist violence around the world today. Since 9/11 Islamic jihadists have perpetrated well over 5,000 terror attacks; no other group even comes close. Sane and courageous law enforcement officials will therefore subject young Muslim males to greater scrutiny, within the bounds of the law — and political correctness can take the hindmost.
