In the days since the Boston Marathon bombings, local law enforcement officials have been given high marks for their response to the attack and the coordination among numerous federal, state and local agencies involved.
But at the same time, questions are being raised about the coordination among federal agencies handling intelligence they had about the suspects in the months before the attack.
The massive swath of Boston that has been closed for more than a week is getting closer to reopening. City officials yesterday brought victims of the marathon bombings and their relatives in for a private visit and allowed neighborhood residents back home for the first time in over a week. Businesses also began the process of cleaning up and preparing to reopen.
The hardest-hit shops and restaurants remain boarded up. As NPR's Tovia Smith reports, others are hoping to reopen today or tomorrow.
As investigators look into the Boston Marathon bombings, one crucial question is whether the suspects, brothers Tamerlan and Dzhokhar Tsarnaev, acted alone or had help. The clues might be found in the bombs used.
From what is now known, it appears the brothers assembled a whole arsenal of explosives. Watertown Police Chief Edward Deveau told CNN last weekend that the suspects had at least six bombs, including the two used in the attack and one thrown at police during a shootout.
Footage from surveillance cameras along the Boston Marathon route gave the FBI early clues about the bombing suspects. And prosecutors say they'll use some of those images to try to prove their criminal case against 19-year-old Dzhokhar Tsarnaev. But the proliferation of cameras in America's big cities is raising some tricky questions about the balance between security and privacy.
It was pictures of two brothers taken by a camera outside the Lord & Taylor department store that provided the first glimpse of the men who allegedly bombed the Boston Marathon.
