Motives for Murder

In Baghdad yesterday, three women wearing suicide vests with bombs killed 24 pilgrims marching in a religious festival and wounded at least 62 others, many of them children.

In Knoxville, Tenn., an unemployed man opened fire with a shotgun, killing two people at a Unitarian church he had never attended. He left a note in his SUV, according to police, about his "frustration" over not finding a job and "hatred of the liberal movement" that the church represented.

The search for serenity through religious worship is not what it used to be.
