Defense expert Dr. Warner Spitz made a comment to the press which seems to question Dr. Jan Garavaglia’s ruling of homicide as the manner of toddler Caylee Anthony’s death. Dr. Spitz’s comment may be found at the following link.

Defense Expert Dr. Warner Spitz: “There is nothing that I know that tells you this was a murder.”
“There is nothing” – This is a weak construction which would have been stronger without the “there is”. For instance, “Nothing I know tells you this was a murder,” would have been a far stronger construction. The weaker the sentence structure, the less the speaker believes what they are saying as they have verbally distanced themselves from their thoughts.
“that I know” – Dr. Spitz’s manages to both distance himself from what he claims to “know” and limit his use of “nothing” to only “nothing” “I know” in three little words. “That” distances Dr. Spitz from “I know”. “Nothing” normally means “nothing”, but now it means something, but not something “I know”. Not only could there be something which does tell us this is murder, the possibility is so strong, Dr. Spitz must give himself a verbal emergency exit in case someone brings up the something which he claims not to know.
“that tells you” – Dr. Spitz again uses “that”, this time to distance himself from what he “tells you”. Dr. Spitz is telling us he is not aware of evidence which indicates Caylee Anthony was murdered, but he is not comfortable with his statement.
“this was a murder” – Yes, “this was a murder”. Not only “was” it a “murder”, it continues to be a murder and will always be a murder. “This” brings Dr. Spitz close to the identification of the “murder”. Dr. Spitz is able to form the phrase “this is a murder” while denying the very fact.
We have learned Dr. Spitz does not want to make a blanket statement Caylee Anthony’s death was not a murder, instead relying on verbal trickery to equate his asserted lack of knowledge with fact.
UPDATE:
Another way to read this quote is to take it literally. He knows nothing that will tell “you” this was a murder, although he may know something which would tell him “this was a murder”. After all, he has training and experience. Most likely, “you” do not.
