Mark Klein이 EFF에 Room 641A를 알린 방법 [도서 발췌]

Mark Klein's disclosure of NSA's Room 641A provided the first concrete evidence that the US government was conducting mass surveillance of domestic internet traffic through telecommunications infrastructure, a practice that operated without public knowledge or legal authorization. This whistleblowing became pivotal because the EFF had previously lacked documented proof to legally challenge these surveillance programs enabled by the Patriot Act; Klein's testimony and supporting documents finally provided the evidence needed to expose constitutional violations. The case illustrates how insider accounts and leaked documentation become essential when institutional oversight mechanisms fail to prevent government overreach.
