Survivors and victims' families have renewed calls for a public inquiry as two reports on the London bombings of 7 July are published.
Survivors believe an inquiry will give them answers
Home Secretary John Reid ruled out the possibility in a statement to the House of Commons, but he has agreed to meet victims' families to explain his reasons.
However, survivor Rachel North told the BBC News website she was "staggered" there would be no public inquiry and dismissed a report by the Intelligence and Security Committee.
"These meetings that led to these reports took place behind closed doors," she said.
"They were internal investigations and I am not surprised that the politicians and security services have examined their work in secret and subsequently found themselves not to blame.
"It is the public - not the spooks or politicians - who walk the streets, take the buses and tubes each day, and wonder what risks they run.
"The public seem to have so many unanswered questions. I find it staggering that there is no public inquiry to answer them."
Robert Webb, from Cardiff, whose sister Laura died at Edgware Road, said a number of issues were not covered by the report.
"If this country is to learn the lessons and move on from this we need a public inquiry,
and I would add my voice to the many voices of other families calling for
"What is important is if the security services did as much as they could have
done, that is a key question.
"And if they couldn't do more because of a lack of resources then that must
be dealt with."
Daniel Biddle, 27, from east London, who lost both his legs and an eye in the Edgware Road bomb, said the release of the report would not help him come to terms with the events of 7 July.
Mr Biddle, who is still being treated in hospital, told BBC Breakfast: "To do a report a year on, it doesn't
help anybody. To turn round and say no one was at fault, it doesn't help the
survivor to get past it.
"To me, there's no justice because the person who's at fault killed himself
when he set the bomb off.
"I can't get a sense of justice from any report. It doesn't enable me to move
Families say the government failed in its duty to protect the public
Graham Russell, whose son Phillip died in the Tavistock Square bus blast, joined calls for a public inquiry.
"We want an investigation into how things were handled when it did happen, because for sure something like this will happen again and they need to be more aware of what happened."
Diana Gorodi, whose sister Michelle died in the Russell Square bombing, said it was impossible to believe the bombers acted alone.
"If we can afford a war in Iraq, surely we can afford to get protected in
England," she told BBC Radio 4's Today programme.
"It's impossible for me to believe that those four individuals acted on their
own and had no links with any terrorist organisation or any kind of radicals
that were picked up by the intelligence earlier on," she said.
John Falding, whose partner Anat Rosenberg was killed in the Tavistock Square bus bombing, said if there was a lack of resources, it showed that the government had failed in its duty to protect the public.
Ms Rosenberg, 39, an Israeli charity worker who was living in Finsbury Park, north London, was speaking on the phone to Mr Falding, 62, when the bomb went off.
Mr Falding said: "It would be wrong to blame the security services too much
because it does appear they were under-resourced. That raises in my mind the
question of why they were under-resourced.
"So much of this inevitably is hindsight and wishful thinking, but there are obvious lessons to be learnt, and let's hope they are being."
But Chris Agwu, cousin of Ojara Ikeagwu, 55, from Luton, who died in the Russell Square bombing, said nothing could be done to stop a "determined" terrorist, no matter how much resources were put in a prevention.
"If they are really determined they will always find a way to get through
once in a while," he said.
"So many lessons have been learnt since the bombings, but when someone's really determined it's really very difficult to stop them."
