From the story here:
The [Inspector General] alert revealed that State Department officials lost contract files and maintained incomplete contract files, thus exposing taxpayers “to substantial financial losses.” Federal law and State Department policy requires maintenance of all files required to document a government procurement from start to finish.
In a blistering summary, the IG alert said such failures create “conditions conducive to fraud, as corrupt individuals may attempt to conceal evidence of illicit behavior by omitting key documents from the contract file. It impairs the ability of the department to take effective and timely action to protect its interests and, in turn, those of taxpayers. Finally, it limits the ability of the government to punish and deter criminal behavior.”
