If liberals are so upset about murdering American citizens with out trial, then where are the talks of recall elections, petitions to congress, trying the president on war crimes, impeachment? The fact is if this was GB they would be screaming about it instead they are proving to be hypocrites and willing to support anything their guy does right or wrong.
Personally I love the world wide assassination program being conducted by the president, but think it should be carried out by carpet bombing in B52s thats much better power projection then a measly drone. However, it is definitely illegal and killing American with no trial or justification is the worst road this country can go down.
