"Just the facts" joke

Justice, American Style
The following exchange happened last March 5 on the show "Politically Incorrect," between Bill Maher, the host, and lawyer Leslie Abramson, who defended the Menendez brothers:
Bill: When do lawyers give a damn about the facts?
Leslie: When did you or Geraldo give a damn about the facts?
Bill: You defended the Menendez kids. What do you care about facts?
Leslie: I don't remember seeing you in the courtroom, Bill, so you absolutely don't know anything about the trial.
Bill: I knew they blew their parents' heads off.
Leslie: No, they didn't. They didn't blow their parents heads off.
Bill: The Menendez kids didn't blow their parents heads off?
Leslie: No!
Bill: What did they do?
Leslie: They unloaded shotguns in their direction.
