Boston is returning to normal after one the biggest manhunts in US police history ended with the arrest of a teenager suspected of carrying out Monday's marathon bombings.
The entire city was under lockdown on Friday as police scoured the area for suspect Dzhokhar Tsarnaev, 19.
He was found hiding in a suburban backyard and detained after an exchange of fire in which he was wounded.
His brother, Tamerlan, was earlier killed in a shoot-out with police.
Three people died and more than 170 were wounded in Monday's bombings and a police officer was shot dead during the search.
Dzhokhar Tsarnaev is being held under armed guard at the Beth Israel Memorial Hospital, where many victims of the bombing are also being treated.
Officials have said they intend to question him without reading him his Miranda rights - the standard statement informing suspects they have a right to a lawyer and to remain silent - citing a "public safety exception".
The decision was criticised by the American Civil Liberties Union, which said such an exemption only applied in the case of immediate threats, and that there was no "open-ended" way in which a suspect could have such rights removed.
"We must not waver from our tried-and-true justice system, even in the most difficult of times. Denial of rights is un-American and will only make it harder to obtain fair convictions," it said in a statement.
But Republican Senators John McCain of Arizona and Lindsey Graham of South Carolina have argued Tsarnaev should be treated as an "enemy combatant", meaning he would not be entitled to the same legal rights as a criminal defendant.
"We should be focused on gathering intelligence from this suspect right now that can help our nation understand how this attack occurred and what may follow in the future," their statement read.
President Barack Obama has promised to seek answers on what motivated the alleged bombers and whether they had help.
'Bittersweet'
The huge manhunt began after police officer Sean Collins, 26, was shot dead in the Cambridge area of Boston. Shortly afterwards a car was hijacked, then a gun battle began further west, in Watertown, injuring one police officer.
Tamerlan Tsarnaev, 26, was fatally wounded - doctors said he died in custody of bullet wounds and possible blast injuries from explosives strapped to his body.
The younger brother fled by car.
Boston was under lockdown throughout Friday, as police scoured Watertown. At 18:00 local time (23:00 GMT) the order was lifted, then an hour later a huge gunfight broke out in Franklin Street, Watertown.
It later emerged that a resident had found a seriously injured Dzhokhar Tsarnaev hiding in a boat in his backyard.
Police say attempts to negotiate with him failed, and he was arrested after an exchange of fire.There were scenes of celebration on the streets of Boston on Friday night. People cheered, honked car horns and waved American flags.
Elliot Friar, who lives close to where Monday's bombs exploded, said it was "a bittersweet moment" because of those who had lost their lives.
"But it was also a time for celebration because the city has been on edge and we're finally feeling more safe than we have in the past four days," he told the BBC.
The governor of Massachusetts, Deval Patrick, thanked the public for their "extraordinary patience and their participation in this investigation".
"It's a night where I think we are all going to rest easy," he wrote on Twitter.
The two bombs, which went off close to the finishing line of the Boston Marathon, killed three people: Martin Richard, aged eight, Krystle Campbell, 29, and Lu Lingzi, 23, a postgraduate student from China.
In a statement, the Richard family said: "Tonight, our family applauds the entire law enforcement community for a job well done, and trust that our justice system will now do its job."
