In 2011 the Joint Special Operations Command executed a planned assassination of United States citizen Anwar al-Awlaki in Yemen. Born in New Mexico, al-Awlaki was an outspoken critic and US Government deemed enemy. In October of 2011, the US Governement carried out another drone attack that killed US citizen and 16 year old Son of al-Awlaki, Abdulrahman al-Awlaki. Neither citizen had a trial nor was one deemed necessary with their declaration as enemy combatives of the United States.
A new report from Jeremy Schaill who helped break the story of drone attacks in Yemen, Somalia and other non-declared war zones, now lists at least 273 civilian causalities killed due to what some deem to be egregious tactics of how the US is targeting, wrongly, it's desired assassination targets, resulting in some attacks only killing civilian men, women and children. This includes missile targeting based solely on cell phone SIM card location, with no first hand verification of the holder of said cell phone.
In the furthering of these drone attacks the US Government is now mulling addition assassination of US citizens including more in non-declared war zones. Some critics of the policy warn of the potential for domestic use of assassination of US citizens without trial due to this provision, so long as the US Government deems someone an "enemy combative". Especially troubling is the fact that drones are already being used within the US borders to carry out enforcement tasks.
