LOS ANGELES — Urging a jury to acquit Phil Spector of murder Thursday, a defense attorney charged that law enforcement officials railroaded the music legend in the death of an actress because they were desperate to win a conviction against a celebrity.

Making oblique references to the unsuccessful prosecutions of O.J. Simpson and Robert Blake, the lawyer told jurors in her closing argument that prosecutors in the Los Angeles County District Attorney's Office disregarded evidence that Lana Clarkson's death was a suicide in order to make Spector the "first celebrity notch in the government's gun belt."

"They had a history of high-profile cases and a history of bad results," Linda Kenney-Baden told jurors, who are expected to begin deliberating a second-degree murder count against Spector Monday.

In a four-hour summation that is to continue Friday, the defense attorney repeatedly implored jurors to conduct their own investigation, setting aside the celebrity status of the defendant.

Spector, 67, faces 15 years to life in prison for the 2003 shooting of Clarkson, 40, in the foyer of his mansion. Prosecutors maintain he shot her because she rejected his sexual advances.

In his closing argument Wednesday, a deputy district attorney argued at length that the scientific case the defense touted before trial was a "checkbook defense," in which paid forensic experts offered biased, unsubstantiated findings. He specifically attacked the testimony of Kenney-Baden's husband, pathologist Dr. Michael Baden, as having no credibility.

But in her address to jurors, Kenney-Baden focused heavily on scientific evidence, including that offered by her husband, whom she called "Dr. Baden." She said the forensic testimony offered by the defense exonerated Spector.

She called the ivory dinner jacket the producer wore the evening of the shooting "probably the most important piece of evidence" in the trial and said it was in itself "proof beyond reasonable doubt that Philip Spector is innocent."

Prosecutors have argued that the presence of tiny blood drops on the left side of the jacket is proof Spector was within three feet of Clarkson when the gun discharged in her mouth, but Kenney-Baden said the blast propelled blood and tissue from her mouth and nose "like a bazooka."

She argued that the sleeves and cuffs of Spector's jacket would have been heavily stained if he were holding the .38 Special revolver in her mouth when it fired.

Those areas, she noted, "were pristine."

She also cited the upward angle of the wound and said that, given Clarkson's seated position in a low chair, "Phillip Spector would have to be kneeling between her legs to get that angle."

"He's short, ladies and gentleman, but he is not that short," she said as the 5-foot, 4-inch defendant looked on from the defense table.
