They can’t just draw names from a hat. Today a federal court will begin weaving through a 1,200-strong pool to find jurors with no emotional attachments to the case. The jury must decide whether Dzhokhar Tsarnaev is guilty of bombing the Boston Marathon finish line in April 2013, killing three and injuring 260. And if so, whether he should face the death penalty. Victims have been waiting nearly two years for justice, and testimony is finally expected to begin next month.
