Real life police and prosecutors have noticed due to the CSI effect real-life criminals have started covering their tracks and are destroying potential evidence against them before leaving crime scenes. One example of this is when double-murderer Jermaine McKinney broke into a house and killed a mother and daughter, he then proceeded to wash blood away with bleach, burn his clothing to destroy evidence, blanket his getaway car to avoid blood transfer, remove his cigarette butts from the scene and attempt to dispose of the murder weapon. McKinney was a big fan of CSI, and this type of calculated behavior is no isolated incident as some rapists have now begun forcing their victims to shower after an attack in order to wash away any forensic evidence. "[These shows] are actually educating potential killers even more," says Head of Los Angeles Homicide Division Captain Ray Peavy. "Sometimes I believe it may even encourage them when they see how simple it is to get away with on television." Peavy isn't alone in his thinking. "[Criminals] do clean up, and they tend to clean up much more carefully now," said Linda Johnson, a crime lab director at Jefferson County, Alabama. "A lot of them know they can use bleach and different detergents to mask our ability to take blood."
