Had it resulted in an admission of guilt even to the lesser charge (accidental death and disposing the body) they would have considered it worthwhile.
What is the immediate question that would have been asked before a "lesser" charge was made?
"What did you do with the body?" springs to mind. Where do you think that might have taken the investigation if armed with a 'confession'?
Why was Mark Harrison eventually called in to advise the investigation? For his expertise and experience, perhaps?
Unfortunately the investigation did not take on board his and the handler's advice regarding the exact significance of the dogs' alerts.
Nor did the investigation seem to understand the importance of having the patience to await confirmation of the results of forensic investigation. Or perhaps they did only too well.
The McCanns were easily accessible ... so why the rush to have them constituted arguido a few days before Portuguese law changes were due to come into effect which would have required firm supporting evidence.
Police 'rushed Madeleine McCann case'A new penal code was introduced on Sep 15

Madeleine McCann’s parents might have been spared the anguish of being named suspects over her disappearance if Portuguese police had not rushed their case through before a change in the law, it has been claimed.
Kate and Gerry McCann were made arguidos - formal suspects - just eight days before new legal measures were introduced which would have required firmer evidence against them.
The couple’s Portuguese lawyer has claimed that detectives may have deliberately fast-tracked the investigation to ensure they were put in the frame.
Investigators named the McCanns, both 39, as arguidos on September 7 after allegedly finding microscopic traces of blood in their holiday apartment and "bodily fluids" they thought could have belonged to Madeleine in the boot of their hire car.
Carlos Pinto de Abreu, a Portuguese lawyer on the McCanns’ defence team, said that under Portugal’s new penal code, police must have more than just suspicions to make somebody an arguido.
"On September 15 a new procedural penal code was introduced making it necessary for there to be evidence against the citizen before they could be made an arguido.
"Before this date it wasn’t necessary. You could be made an arguido without actual evidence against you," he said.
"Maybe that is why the investigation took the turn it did - why they were named arguidos eight days before the new laws came in," said Mr Pinto de Abreu.
His comments followed those of Fernando Jose Pinto Monteiro, Portugal’s Attorney General, who recently admitted the McCanns may not have been made suspects under the new laws.
"At the time when the McCanns were made 'arguidos' the law did not demand justified suspicions. I do not know if they would be (arguidos) in light of the new Code," he said in an interview with the Portuguese magazine Visao.
Clarence Mitchell, the official spokesman of the McCanns, said he hoped the introduction of the new law would work in their favour.
"Being declared arguidos almost three months ago caused the McCanns’ immense anguish and continues to do so," he said.
"To think they could have been saved that under a law introduced only days later makes a mockery of the case against them.
"They are entirely innocent victims of a horrible crime that has taken away their daughter and they want to be cleared as soon as possible so the focus can return to finding Madeleine.
"If it is true that changes to the law would have meant that they would not have been made arguidos that’s all the more reason for their status to be dropped now.
"Regardless of any changes in the law they should be eliminated forthwith from the inquiry."
Portuguese police were told last week that forensic results requested from Birmingham’s Forensic Science Service had so far proved "inconclusive".
They plan to travel to Britain next week to re-interview the McCanns and the seven friends who dined with them at the Tapas restaurant on the night of May 3, when Madeleine went missing from the holiday apartment in Praia da Luz.
