Going off topic, explains a lot about the Cipriano case.
I'm not sure you have gone off topic there.
Goncalo Amaral's hands were tied when it came to the previous missing child case he and his team had worked and Madeleine McCann's case.
Just as Scotland Yard have taken home invasions which occurred throughout the region very seriously indeed the fact that another child went missing in a neighbouring town was worthy of a closer look when Madeleine too disappeared.
We have all seen the fictional TV detectives in front of maps which pinpoint similar incidents which may or may not be related to the case under investigation. I believe something similar happens in real life casework.
Not in this case though, without calling attention to the fact there may have been a miscarriage of justice in one.
The solution to that appears not to have been a positive one of looking for two children missing a few miles apart who might very well still have been alive ... but to set the stage based on poorly understood forensic work to ensure a second miscarriage of justice.
So in my opinion ... not in the slightest "off topic" as I think it goes a long way to understanding the misinterpretation of the evidence when a comparison of both cases with the same lead detective in charge is made.
