There has to be an intention to abandon for arrests to be made. According to the PT AG there was none.
Quote from Final Report:
In the case of the files and facing the elements that were collected it is evident that none of the arguidos Gerald or Kate acted with intent.

This was in a report, so it wasn't mentioned,doesn't make it untrue, just that it wasn't mentioned. Also, the facts would have to be established in a court of LAW.
A court would establish if the parents were acting responsibly or not and as a child was 'abducted by paedophiles' There would be a strong argument to suggest the parents did indeed put their children in danger by
1. leaving them alone night after night
2 leaving a door unlocked!
3 not doing physical checks or having a ridgid timeline to do said checks.
4 having a child who has 'disappeared' is evidence!
In a court OF LAW this would be blown right out of the water! AND Tapas team know all this! Why else would they refuse to fo back for a reconstruction?
