NEW ORLEANS -- The widow of NFL star Will Smith took the stand Tuesday at the murder trial of her husbands killer, disputing the defense claim that Smith was the aggressor and telling the jury, He didnt have to do that to my baby.Racquel Smith said she thought she had defused the loud, profane argument that broke out after Cardell Hayes Hummer rear-ended Smiths Mercedes SUV on a busy street in New Orleans last April.The men got out of their cars to challenge each other, but she described locking eyes with her husband, reminding him of their three children and feeling his anger diminish.I thought it was done and I think he thought it was over, too, she testified as she was questioned by New Orleans Assistant District Attorney Laura Rodrigue.Then, she heard two gunshots.I hear a pop, pop, she said. I didnt think it was me.A burning sensation spread throughout her body, and as she stumbled around to the other side of their car, she said she heard more gunshots -- the ones she learned later had killed her husband.I didnt do anything for you to shoot me, she told Hayes.Her recollections presented a vastly different picture from the one being outlined by the defense. She insisted that she heard Hayes yelling profanely after the shooting, apparently at her husbands lifeless body, making a reference to a white friend of the Smiths who also got out to challenge Hayes.You want to show up for the effing white boy, she recalled Hayes shouting.Anticipating her testimony, the defense had already disputed that claim in opening statements. They also insisted that Hayes felt threatened by Smith and his friends, who were traveling together in three cars that night after the Smiths attended the annual French Quarter festival, had dinner at a steakhouse and then met friends at a sushi restaurant.On cross-examination just before Tuesdays proceedings ended, Racquel Smith acknowledged that her husband had had alcoholic beverages throughout the day of the shooting, beginning with one at the festival, more at a bar they visited later, wine with dinner and more drinks at the sushi restaurant.Lawyers have said a toxicology report showed Hayes was legally drunk the night of the shooting. But Racquel Smith insisted her husband did nothing to provoke the gunfire.Attorneys on both sides have suggested that Louisianas stand your ground law will be at issue during the trial. Hayes, 29, faces life in prison if convicted of second-degree murder. Hes also charged with attempted murder after woundin
