As O.J. Simpson's defense attorney in the highly publicized 1995 murder trial, Johnnie Cochran played a crucial role in securing Simpson's acquittal. Cochran effectively challenged the prosecution's evidence, famously coining the phrase "if it doesn't fit, you must acquit," and capitalized on racial tensions to sway the predominantly African-American jury. His charismatic presence and strategic defense tactics were instrumental in the trial's outcome.
