Define "Shouldn't"?

I ran across another blawg this morning, "Arbitrary and Capricious." He's got a post up about an idiot paralegal who just thought he'd pretend to be a lawyer for a while. The guy did some serious damage to a "client's" case by advising him to talk to the police when he should've kept his mouth shut. Now the "client" is on trial for capital murder. This is a horrendous situation and it's a good thing Dejeans is facing the consequences of his actions. But something struck me odd in the narrative:

Jimmy Scoggins says his son is in jail facing capital murder charges in large part because of Mr. Dejeans' legal advice. Timothy Scoggins... turned to Mr. Dejean for help when he learned that Dallas police wanted to talk to him about a drug-related quadruple homicide... Mr. Dejean advised the younger Mr. Scoggins that police were interested in him only as a witness to the robbery and shooting and accompanied him to give a statement to detectives.

"He told me that we didn't have anything to worry about, that everything would be all right and the detective didn't want my son for anything but a witness," Jimmy Scoggins said. He said he and his son thought Mr. Dejean was an attorney.

According to court records, Mr. Scoggins told police he had been present during the robbery as a lookout and had carried a shotgun and fired at a fleeing car. Mr. Scoggins was arrested a few weeks later and charged with capital murder... Mr. Scoggins faces life in prison or the death penalty if convicted... His statement would be critical in his prosecution because the only evidence linking Mr. Scoggins to the crime is the statement of a co-defendant...

"My son's in a situation now that he shouldn't even be in because his case was handled by someone who isn't even a lawyer," Jimmy Scoggins said...

(Emphasis mine.) Which brings me back to the title of the post: define "shouldn't"? Could it be that at least in the cosmic/karmic sense, your kid's getting exactly what he deserves? Just a thought.
