Indeed they should ... maybe even run them to the local hospital themselves ... I'm sure I can't think of anything else which might be preoccupying them ~ wait a minute though, wasn't their three year old daughter missing???
The police were in charge ... the police should have taken the appropriate action ... however, why miss the opportunity to metaphorically beat the McCann's up at any juncture ... don't forget they did go out and leave their children unattended.
There, that will save you the bother of 'reminding' us ... but I'm sure you won't let that hinder you.
I have stated before, that the police and the parents should have had the children checked for drugs.
Read over my past posts in regard to that..
As to not having time to take the children to a hospital to be tested, perhaps, just perhaps, instead of resuming jogging, tennis, visiting other countries and meeting 'celebrities, in the aftermath of Madeleine's disappearance, they could have done that themselves.
The none independent tests some 6 months later were irrelevant, and not independently supervised.
