Patriot Acts: Narratives Of The Patriot Act
Sadly, you are right. Even sadder still is the fact that Brandon Mayfield is not the only one going through this injustice. In a report by Human Rights Watch and the American Civil Liberties Union in the year 2002, since the 9/11 attacks, at least 70 men have been detained due to terrorism-related suspicions. Except for one man, all of them are muslims. Most of them are held without charges, access to lawyers or the basis of their arrest. Even if they were released, they still have to wear tracking bracelets and their rights to privacy taken away.
The report can be accessed here or a summary of it here.
If you are interested, there is a book of collected accounts from victims of this misuse of power titled Patriot Acts: Narratives of Post-9/11
injustice by Karen Korematsu. There is also a shorter review done by Gabriel Daniel Solis(here).
