Final answer:
The person named Gideon associated with reading names at the 9/11 memorial service appears to be a case of mistaken identity. The Gideon mentioned from the book 'Gideon's Trumpet' is not related to the 9/11 events. Those selected for reading at memorial services are typically connected to the incident in a significant way.
Step-by-step explanation:
The question seems to be based on a misunderstanding. Gideon, referenced in context to the book Gideon's Trumpet, is not the same individual who would have read names at the 9/11 memorial service. The book tells the story of Clarence Gideon's fight for his right to legal representation, which is unrelated to the 9/11 events. People who participate in reading the names at memorial services are often survivors, victims' relatives, or notable figures who share a connection to the tragedy or represent the collective sentiment of mourning and remembrance.
The outpouring of altruism and heroism following 9/11 witnessed many individuals stepping forward to support communities, including an increase in military enlistments and significant charitable contributions for the relief efforts and families affected by the tragedy. This collective response was emblematic of the nation's unity and resilience, and it is in such a spirit that individuals are chosen to partake in remembrance ceremonies like the 9/11 memorial service.
