Twenty-five years after the September 11 attacks, families of the victims continue to grapple with the absence of a trial for the alleged mastermind, Khalid Sheikh Mohammed. The prolonged legal process has led to frustration and a sense of betrayal among some relatives.

"My overall feeling is a sense of betrayal from the US government and a sense of extreme frustration," said one individual identified as Eagleson. "They've botched every single part of this trial."

As the 25th anniversary of the attacks nears, the wider public perception of 9/11 is shifting towards it becoming a historical event, according to Eagleson. This contrasts with the ongoing personal impact on those directly affected, for whom the event remains a constant presence.

The trial, expected to last approximately a year, is scheduled to take place at a military court at Guantanamo Bay. Professor Kasey McCall-Smith noted that pre-trial proceedings are crucial for determining the admissibility of evidence, which can help expedite the trial itself. "If that is agreed in advance, the trial can be more expeditious," she explained.

For some, like Gerhardt, the prolonged legal proceedings mean continued travel to Guantanamo Bay. He expressed a desire for the trial to conclude so he can move forward. "It's a place I don't want to come back to. I want to live my life, enjoy my passions and my memories of Ralph," he said.

The U.S. government has been involved in the legal proceedings related to the 9/11 attacks for years, including the detention and prosecution of individuals accused of involvement.

The legal proceedings have faced numerous delays and challenges, impacting the timeline for justice for the victims' families.
