Cricket has long been considered the gentleman’s game — a sport in which the tenets of fair play and respect for authority are so revered that it introduced a colloquialism to describe something unacceptable: "It’s just not cricket." Cricket fans around the world found themselves shaking their heads and muttering just that Tuesday morning, after gunmen in Pakistan opened fire on a bus carrying members of the Sri Lankan national team on their way to a stadium for a match. At least six security people were killed and at least eight members of the Sri Lankan team were wounded in the well-coordinated attack in the eastern city of Lahore. No one immediately claimed responsibility.
