Johnnie Cochran Jr. was a prominent African American lawyer who became well-known for his high-profile cases, particularly his role as the lead defense attorney for O.J. Simpson in the famous O.J. Simpson murder trial in 1995. Cochran's charismatic and skillful courtroom tactics, including his memorable line "If it doesn't fit, you must acquit," helped secure Simpson's acquittal.

Prior to the Simpson trial, Cochran was already a respected civil rights attorney who had success in cases involving police brutality and civil rights violations. He also represented prominent figures such as Michael Jackson and Tupac Shakur.

Cochran's work as a lawyer had a significant impact on the legal profession and the fight for racial justice in the United States. He was also a vocal advocate for diversity and equality in the legal field. Despite his passing in 2005, Johnnie Cochran's legacy continues to inspire aspiring lawyers and activists to fight for justice and equality.
