Final answer:
Critics of preventive detention, particularly at Guantanamo Bay, argue it violates basic human rights and legal protections, and undermines U.S. standing. Legal cases like Rasul v. Bush and Hamdi v. Rumsfeld challenged these practices, reinforcing the importance of due process and habeas corpus rights.
Step-by-step explanation:
Some critics have directly opposed the use of preventive detention, particularly in context with the detentions at Guantanamo Bay during the Bush and Obama administrations. They argue that such practices deny detainees' fundamental rights, such as the right to a fair trial and habeas corpus as protected under Section 9 Clause 2 of the U.S. Constitution. Critics also contend that labeling detainees as 'unlawful combatants' to circumvent the protections offered by international treaties, such as the Geneva Conventions, is unethical and diminishes America's global standing.
Rasul v. Bush (2004) and Hamdi v. Rumsfeld (2004) were significant legal challenges to these practices. The former affirmed the federal courts' authority to determine if foreign nationals held at Guantanamo were wrongfully imprisoned, while the latter ruled that U.S. citizens designated as enemy combatants must have due process rights and the ability to challenge their status before an impartial authority.
Critics express concerns that such detainment policies are counterproductive, possibly fueling the recruitment efforts of terrorist organizations, and suggest that a robust civilian justice system is critical for maintaining the rule of law and upholding human rights - reflecting a broader debate on the balance between national security and individual liberties.
