<human>:  In the recent acquittal of George Zimmerman, how did the judge rule?
<bot>: The judge ruled that the DNA evidence was inadmissible hearsay. Hearsay is an out-of-court statement offered to prove the truth of the matter asserted. In this case, the judge ruled that the jury could not consider the DNA evidence because the police officer who collected the DNA evidence had not been available to testify at trial. The judge also ruled that the DNA evidence was not admissible because the police officer did not follow the proper procedure for collecting the DNA evidence.
