"You've got people who are looking at DNA evidence and other evidence like that and they're ignoring it"

This quote by Joseph Wambaugh is referring to making use of DNA proof in criminal cases. He is suggesting that some people are not taking into consideration the evidence that is offered to them, such as DNA proof. He is implying that these people are not appropriately considering the evidence that is available to them, and rather are depending on other types of proof that may not be as reliable. This can be a recommendation to the reality that some individuals might be counting on inconclusive evidence or witness testimony, which can be undependable. Wambaugh is recommending that these individuals ought to be taking a look at the DNA proof as well as various other kinds of proof that are readily available to them, and also not ignoring it. He is emphasizing the value of taking into consideration all the evidence that is readily available in order to make an educated decision.
