Most Americans believe the Libyan government may have had something to do with the murder this week of the U.S. ambassador there and are not confident that the Libyans will punish his killers.

A new Rasmussen Reports national telephone survey finds that 51% of American Adults think it’s likely the government of Libya was involved in the murder of Ambassador Christopher Stevens and three other Americans. Thirty percent (30%) consider that unlikely. This includes 31% who say it’s Very Likely the Libyan government was involved and just seven percent (7%) who believe it’s Not At All Likely. Nineteen percent (19%) are not sure. (To see survey question wording, click here.)
