No loss, he ceased being both snarky and creative years ago.
I was living outside Dallas back in 1976 when Haynes defended multimillionaire oilman Cullen Davis for the execution style murder of his preteen stepdaughter. Both his soon-to-be ex-wife and her boy toy, as well as a visiting neighbor, were shot the same night in the family mansion. IIRC, the boy toy also died, the neighbor was paralyzed, but the wife recovered.
It was called the trial of century in the Metroplex area. Davis looked as guilty as OJ Simpson going in, but Haynes got him acquitted by destroying the wife's credibility on the stand. He painted her as the ultimate gold digger, with particularly emphasis on her drug and alcohol issues (making her an unreliable witness) and her infidelity.
A few years later, Davis got arrested for trying to hire a contract killer to murder his by then ex-wife and the judge who presided over his previous murder trial. Despite a recording of Davis telling an undercover cop he wanted to kill the ex-wife and judge, Haynes again got him acquitted.
The media storm that was generated by the Texas sized murder/trial did not go unnoticed by the TV people. A year or so after the trial, CBS introduced what would become the perhaps the most successful US nighttime soap of all time, "Dallas." Lots of sex and infidelity in that series about a wealthy Texas oil family. The J.R. Ewing character was supposedly based on Davis.
