The US came under sharp criticism at the UN human rights committee in Geneva on [March 13] for a long list of human rights abuses that included everything from detention without charge at Guantnamo, drone strikes and NSA surveillance, to the death penalty, rampant gun violence and endemic racial inequality. The experts raised questions about the National Security Agency's surveillance of digital communications in the wake of Edward Snowden's revelations. The committee's 18 experts [are] charged with upholding the International Covenant on Civil and Political Rights (ICCPR), a UN treaty that the US ratified in 1992. The US came under sustained criticism for its global counter-terrorism tactics, including the use of unmanned drones to kill al-Qaida suspects, and its transfer of detainees to third countries that might practice torture, such as Algeria. Committee members also highlighted the Obama administration's failure to prosecute any of the officials responsible for permitting waterboarding and other enhanced interrogation" techniques under the previous administration. Walter Klin, a Swiss international human rights lawyer who sits on the committee, attacked the US government's refusal to recognise the convention's mandate over its actions beyond its own borders. The US has asserted since 1995 that the ICCPR does not apply to US actions beyond its borders - and has used that "extra-territoriality" claim to justify its actions in Guantnamo and in conflict zones.
