The New York Times has a beautiful interactive feature with audio narratives from "some of the people seen near the finish line." What is most striking about the interactive design: as you scroll down the page to listen to each story, you see where each person was in the still image from NBC's broadcast of the race. Powerful. Here's how the Times put it together. Read the rest

Responding to claims from the mother of the two Boston bombing suspects, the FBI said today it had not been tracking her oldest son, nor had the bureau spoken with him last week after the deadly marathon bombing. The only communication the FBI claims to have ever had with Tamerlan Tsarnaev "was an interview agents conducted with him in 2011 at the urging of a foreign government, since identified as Russia."

Below, an array of perspectives on what legal rights the 19-year-old American citizen suspected of co-executing the Boston Marathon bombings has, and whether law enforcement is obliged to honor those rights under the circumstances:

• "If captured, I hope [the] Administration will at least consider holding the Boston suspect as [an] enemy combatant for intelligence gathering purposes.

According to his friends, University of Massachusetts sophomore Dzhokhar Tsarnaev worked out, slept in his dowm room, and hung out with fellow students on the same day of the attack on the Boston Marathon, after the bombs went off.

“He was just relaxed,” she said.

Depending on which acquaintance's quote you read, the 19-year-old either sounds normal or creepy:

Emily DeInnocentis, 23, said Tsarnaev stood out to her because of some odd behavior, like spreading messy string cheese all over her couch, and picking up her cat and carrying it upstairs for no reason.

“We just didn’t invite him over after that. How many people just pick up your cat and go upstairs?” she said.

Massachusetts state police released this video shot from their airwing helicopter hovering over a boat where the second Boston Marathon bombing suspect was found.

"A large percent of the reaction in Boston has been security theater," writes Popehat. "'Four victims brutally killed' goes by other names in other cities. In Detroit, for example, they call it 'Tuesday.'...and Detroit does not shut down every time there are a few murders. 'But Clark,' I hear you say, 'this is different. This was a terrorist attack.'
