Waterboarding is a controversial interrogation technique that simulates drowning. The person being interrogated is strapped to a board, and water is poured over their face, creating the sensation of suffocation. This method is designed to induce extreme fear and panic, making it a highly debated practice in terms of ethics and legality. Critics argue that waterboarding constitutes torture and violates human rights, while supporters claim it can be an effective means of obtaining information. Various international laws and conventions, such as the United Nations Convention Against Torture, address the use of such techniques, leading to ongoing discussions about their moral implications.
