(Al Jazeera) This week, whistleblower and former US state department investigator, Aurelia Fedenisn, made some significant allegations about the culture of cover ups in the department, when she turned over documents to a Republican senator.

Among the revelations from the leak of state department memos is that an investigation into the killing of four people in Honduras, including a young boy and two women, was quashed.

They were shot from state department helicopters while traveling on a boat carrying 16 people near the Honduran village of Ahuas last May.
