A man who lost his daughter in the London bombings has criticised the government for being "too blase" about security before the 7 July attacks.
Aldgate was one of the stations damaged in the bomb attacks
John Taylor, whose daughter Carrie, 24, died at Aldgate, said lessons should have been learned from the 11 September 2001 attacks in the US.
He told Met Police chief Sir Ian Blair at a conference: "I think we allowed it to be dropped too much."
Mr Taylor, of Billericay, Essex, told reporters he felt "extremely angry".
Mr Taylor, 56, a security manager who used to work at the Tate Gallery, was among several relatives of London bomb victims attending the Together Against Terror? conference in the capital.
Speaking later, Mr Taylor said: "Before 9/11 the threat had been building up for a long time and the attacks of 9/11 in New York told us that the threat was real, clear and present.
"We stepped up our security for a while but it appears to me though the government became a little bit blase about security.
"We should have had our foot on the pedal fully down."
He said there should have been tighter control on extremist preachers, whom he said had been allowed to preach hatred on the streets.
He said: "As soon as anybody starts to do something about it somebody sticks their hands in the air and says 'What about their human rights?' What about the human rights of my daughter and the 50-odd people on July 7?"
The conference, was held at Central Westminster Hall, central London.
