I've actually wondered about this...By JOE MILICIA

CLEVELAND — When Tammy Klein began investigating crime scenes eight years ago, it was virtually unheard of for a killer to use bleach to clean up a bloody mess.
Today, the use of bleach, which destroys DNA, is not unusual in a planned homicide, said the senior criminalist from the Los Angeles County Sheriff's Department.
Klein and other experts attribute such sophistication to TV crime dramas such as "CSI: Crime Scene Investigation," which give criminals helpful tips on how to cover up evidence.
Prosecutors have complained for years about "the CSI effect" on juries: an expectation in every trial for high-tech forensic evidence.
It also appears the popular show and its two spinoffs could be affecting how some crimes are committed.
