military interrogators in the art of
statement analysis, said Cameron's
overall statement appeared truthful but
that the part about leaked blood
warranted further investigation.
It was an "area of concern", according
Like cadaver dogs, statement analysis is

McClish told Nine.com.au that careful
examination of words, phrases and

"Deceptive people will sometimes use
synonyms because they are making up a
portion of their story they cannot
relate to and consequently do not always
follow their personal dictionary."
Throughout his statement, Cameron used
the word "vehicle" to describe the
Renault until he reaches the point where
he talks about the odour. Then the
