SANFORD, Fla. -

The judge in the George Zimmerman case ruled Tuesday that the entire jury pool will not be sequestered as suggested by the defense. 

Zimmerman's attorney, Mark O'Mara, argued at a hearing that the best way to find a fair jury would be to sequester all 500 prospective jurors.
    
O'Mara said he wants to "assure (the jury) is free to acquit without feeling any pressures."
    
O'Mara also said that in regard to the cost of a sequestered jury, which he called a "sequestered jury on steroids," that there is "no greater cost than diminishing my client's right to a fair trial."

State prosecutors, however, said sequestering all potential jurors is "unrealistic."

Judge Debra Nelson said prospective jurors will be referred to by their juror numbers and no pictures will be taken, but the prospective jury will not be sequestered as a whole.

Zimmerman is charged with second-degree murder in Trayvon Martin's death.  Zimmerman has pleaded not guilty, claiming self-defense.
