TALLAHASSEE -- While courts wrestle with the question of Thomas Provenzano's sanity, Mark Parker waits for the execution of the man who shot him 15 years ago, leaving him paralyzed from the shoulders down.

From his vantage point, the issue seem clear.

``He was sane enough to plan it out for two or three weeks,'' Parker said, referring to Provenzano's 1984 shooting spree in an Orlando courthouse. ``He brought a gas mask, I assume to be prepared to deal with the SWAT team if he got into a barricaded situation. He brought extra ammo.''

Provenzano was an unemployed electrician when he walked into the Orange County Courthouse in January 1984 armed with a shotgun, an assault rifle, a revolver and a knapsack carrying ammunition, all hidden under a large Army-style jacket.

He muttered threats against two police officers who had charged him with disorderly conduct five months earlier. When a bailiff approached to search him, Provenzano shot the bailiff and two colleagues. One of the victims was Parker, who was 19 at the time.

Provenzano's other victims were William Wilkerson, a 60-year-old who had retired from the Navy 14 years earlier as a lieutenant commander, and Harry Dalton, a 53-year-old father of six. Wilkerson died immediately; Dalton was paralyzed and died seven years later.

Provenzano was clear-headed enough to pick his targets when he opened fire, Parker said.

``He only went after law enforcement,'' he said. ``He knew what he was doing. If he's gone insane while in jail, that's his problem.''

Florida law, however, bars execution of an insane person, based on the constitutional ban on cruel and unusual punishment. The Florida Supreme Court on Thursday gave Provenzano his fourth stay of execution this summer, directing a retired judge to hold another hearing into his claim of insanity.

A Wyoming psychologist has said Provenzano believes he is Jesus Christ and faces execution because of that.

Earlier this month, a trial judge ruled Provenzano, 50, has the mental capacity to understand why the state is trying to execute him. But the judge didn't extend the hearing to allow the Wyoming psychologist to testify, which Florida's high court said was a mistake big enough to require another hearing.

Another trial judge ruled last month that the electric chair is constitutional. The state Supreme Court upheld that decision Friday. But the question doesn't interest Parker.

``As far as it being cruel and unusual punishment, he was an electrician, he knows how it feels,'' Parker said after the high court granted Provenzano his latest stay.

Parker said his reaction to the latest reprieve was ``nothing you can put in the paper.''

But then he finds some words that can be printed and he repeats one -- ``ridiculous'' -- several times as he discusses the reprieve.

``It's definitely becoming monotonous,'' he said. ``I can't understand what they're holding off on, what's their excuse this time. Fifteen years ago, he was found guilty of premeditated first-degree murder, he was sentenced to death by a judge.''

Now 35, Parker said he won't stop making plans to witness Provenzano's execution -- whenever it happens.

``If they execute him before we all die of old age, I'll plan on going to it.''
