After placing the city of Boston on lockdown, police captured the second suspect in the Boston Marathon bombings late on Friday. Nineteen-year-old Dzhokhar Tsarnaeva was found hiding in a boat docked in a backyard after a citywide sweep by SWAT teams, military Humvees and police dogs. The other suspect, his older brother, died after a car chase and police shootout. We get the latest news from Boston, and discuss how the brothers' suspected involvement in the bombings and their Chechen roots will affect homeland security and beyond.
