Since 2011 when U.S. citizen al-Awlaki was killed in a drone strike, various civil rights groups (and family members) have sought to obtain (and challenge) the legal justification for the strike. The issue gained further notoriety in early 2013, when Attorney General Eric Holder refused to rule out a lethal drone strike on U.S. citizens on U.S. soil. Analysis of the justification by interested parties is likely to follow – as are, potentially, more lawsuits.
