Atlanta ? The deputy, a 51-year-old woman just 5 feet tall, was simply no match for the inmate she was escorting to the courtroom, a 6-foot-1, 200-pound former college linebacker on trial for rape.

Authorities say Brian Nichols overpowered deputy Cynthia Hall, took her gun, and easily gained access to the courtroom, where he went on to kill the judge and a court reporter. Security cameras captured images of him overpowering the deputy, but no one, it turned out, was watching the screens.

There were more security gaffes. Earlier in the week, Nichols was found to have had two homemade knives in his shoes while in court. And the vehicle reported to be his getaway car was found more than 13 hours after the shootings — in the same parking garage where it was allegedly carjacked.

Authorities are investigating how the security breakdowns happened on that bloody Friday morning, and they are vowing changes will be made. The issue is getting national attention as well, with Sen. Arlen Specter, chairman of the Senate Judiciary Committee, saying he would hold congressional hearings on improving security at courthouses and for judges.

Among the issues being looked at in Georgia are better training, increasing deputy staffing, requiring inmates to be handcuffed in the courtroom and a security standard that would apply to every courthouse in the state.

“You go to courthouses across Georgia, you would find everything from high security to no security,” said state Sen. Joseph Carter, a lawyer. “I’ve been to courthouses where they see you in a suit and they say, Are you an attorney? Come on in.’ You appreciate the courtesy, but that always gives you a little pause.”

The heightened security is the result of what happened when Nichols, 33, allegedly went on a rampage as he was being taken to the courtroom for his rape trial. In addition to the judge and court reporter, he is accused of killing a deputy outside the courthouse and a federal agent while he was on the run. Nichols surrendered Saturday after a woman he had taken hostage apparently coaxed him into it.

Owens was one of the first responders at the scene of Friday's fatal shootings of Judge Rowland Barnes, court reporter Julie Brandau and Sheriff's Sgt. Hoyt Teasley at the courthouse.

Sheriff’s spokesman Lt. Clarence Huber declined to elaborate on what security changes were made at the Fulton County Courthouse when it reopened Monday. But longer lines at a checkpoint near the entrance indicated more thorough searches.

Prosecutors actually had asked for increased security surrounding Nichols last week after he was found with the homemade knives — one crafted by a door hinge, another from piece of metal “the size of a TV remote,” said Barry Hazen, the suspect’s attorney in his rape trial.

Authorities have said Nichols was not in handcuffs or shackles as he was being moved to the courtroom because they did not want to taint the jury by showing him in restraints.

The U.S. Supreme Court has held that people on trial can be shackled in front of the jury, but only if prosecutors have a strong argument for it. Prosecutors could very well have won that argument in Nichols’ case because of the knives.
