Boston Mayor Thomas Menino revealed he thinks the Tsarnaev brothers acted alone when they terrorized Boston over the last five days during an appearance on ABC's This Week. "All the information I have is they acted alone," he said. He also called on the U.S. attorney's office to "throw the book" at the surviving brother. "I hope that the U.S. attorney, Carmen Ortiz, takes them on the federal side and throws the book at them," Menino said. "These two individuals held the city hostage for five days." Menino also defended shutting down the city on Friday while authorities searched for Dzhokhar Tsarnaev. "I had information that there was other things going on," he said. "I agreed with that decision at the time."

Boston Police Commissioner Ed Davis offered an update on the condition of 19-year-old suspect Dzhokhar Tsarnaev during his appearance on Fox News Sunday. "He’s in no condition to be interrogated at this time," Davis said. "He’s progressing, though, and we're monitoring the situation at this time." Dzhokhar is in stable but serious condition at a Boston hospital right now. Investigators are waiting to question him until his wounds have healed enough to speak with a special interrogator. Davis said the imminent threat is over, but cautioned that new developments may arise once the suspect is questioned. "There may be other components of this investigation that will lead to charges down the road," he said. Davis couldn't say definitively whether the older brother, Tamerlan, was the leader in the plot. He did theorize that the brother went on another crime spree Thursday -- killing an MIT police officer and carjacking an SUV -- because the FBI released their photos. "I think they decided to go active after their pictures were disclosed publicly," he said. "I think that’s what started the rampage."

Massachusetts Gov. Deval Patrick told CBS's Face the Nation host Bob Schieffer that he doesn't expect any political backlash for shutting down the city for a whole day while authorities tried to track the bombing suspect. "I think people understood that we were making decisions in the face of a rapidly developing investigation and that we were making them in the best interests of people's public safety,” Patrick said. Schieffer asked if Patrick feared people ignoring the order and venturing into the great outdoors, to which the Gov. said he was "fully aware that there are knuckleheads out there." He did thank the public for cooperating with the order, for the most part, and for cooperating and helping with the investigation. 

Sen. Dianne Feinstein took an interesting position on Fox News Sunday. The influential Democrat said she agreed with the decision to invoke the "public safety exception" so Dzhokhar Tsarnaev could be interrogated before being read his Miranda rights. But she does not agree that Tsarnaev should be tried in a military court. He should eventually be read his rights and tried as a civilian, she argued. "It would be unconstitutional to," try him as an enemy combatant in military court, she said. Feinstein argued law enforcement have more than enough evidence to convict him in civilian court and could even potentially secure a death penalty conviction. "It should likely be a death penalty case under federal law," she said. 

Sen. Chuck Schumer thinks the death penalty would be "appropriate" and still apply in Dzhokar Tsarnaev's case. The New York Senator told CNN's State of the Union host Candy Crowley that he still supported the use of the death penalty here despite it being illegal in Massachusetts. If he's tried federally then it could still apply, Schumer argued. "The federal law allows the death penalty," Schumer said. "I wrote the law in 1994 when I was head of the crime subcommittee in the House. This is just the kind of case that it should be applied to." He did leave some room for the chance that he might be wrong, though. "Given the facts that I’ve seen, it would be appropriate to use the death penalty in this case," he said.

Sen. Lindsey Graham sees holes. He sees holes in the F.B.I. He sees holes in U.S. law. He potentially sees holes everywhere. But these are the ones he's focusing on right now, he told Candy Crowley on State of the Union. "The ball was dropped in one of two ways," the South Carolina Republican explained. "The FBI missed a lot of things, is one potential answer, or our laws do not allow the FBI to follow up in a sound solid way." Graham argued that Tamerlan Tsarnaev should have been on the FBI's radar because of his trip to Russia and his online activity relating to 9/11 conspiracy theories. "It’s people like this that you don’t want to let out of your sight, and this was a mistake," he said. "Either our laws are insufficient or the FBI failed, but we’re at war with radical Islamists and we need to up our game."

Former White House counter-terrorism adviser Richard Clarke wondered aloud if there may be copycat terrorists in the wake of the Boston bombings on ABC's This Week. "Now that people have seen what two men can do with easily obtainable materials -- close down a city, get the president of the United States to show up," Clarke said. "Other people around the country who have been radicalized have watched this, and they're going to wonder, is there a way now that I can do this?" Clarke worked under Bush and Clinton but never under Obama. He also wondered what Russia did once Tamerlan Tsarnaev travelled to the country. They had suspicions that he was a potential threat and asked the FBI for information. When the FBI investigation didn't turn up any clues, Tsarnaev travelled to Russia. "What I want to know is what did the Russians do when he went back to Russia?" Clarke said. "What did they do, did they follow him around?"
