The Metropolitan Police, which serves Greater London, says that it has made efforts to provide information, but that it is painstaking work, hindered in some cases by inaccurate and unreliable official records. But the paucity of official information about the fire dominated a series of meetings last week between residents and the authorities.

“If this was a terrorist attack, they would have had the numbers out here already,” said Beinazir Lasharie, a Labour member of the Kensington and Chelsea Council who represents the neighborhood that includes the tower. “They need to tell us the truth, because the people are angry and they’re getting angrier.”

From the day of the fire, June 14, when the death toll was initially announced as only six and later 12, people began to complain that the police were giving low estimates. It was clear that flames had engulfed the entire building in a very short time, forcing some — no one has divulged how many — to jump out of higher floors and others to flee down the single, smoke-choked staircase.

The death toll was raised to 17 on June 15, to 30 on June 16, to 58 on June 17, to 79 on June 19, finally reaching 80 on June 28, where it has stayed since. On July 5, the police added that they had recovered 87 sets of human remains, but could not say for sure how many people that represented.
