'The McCanns have explained that they believed their system to be safe, that it was based on the professional systems but modified'.
What professional systems ?
Anyone in hindsight can say they did wrong, but that does not excuse behaviour.
How is it 'professional' to leave children in an unlocked apartment and be safe ?
They are mutually exclusive events.
You are clearly picking and choosing what posts to read as I have already replied to you.
I was referring to the professional holiday company systems.
The McCanns in their explanation stated that they believed that the system was safe because it was based on those company practices.
I have never excused the leaving of the patio doors open but I have been very clear that simply doing that is not proof that (as you claimed in another thread) the McCanns are wholly responsible for what happened. That is simply untrue.
The reality is that if an abduction took place the abductor bears responsibility too.
And you are deliberately ignoring the fact that the AG has cleared the McCanns of this neglect/abandonment which you continually ascribe to them.
Your posts take no account of the practices current at the time, nor of the fact that the McCanns have been cleared by the Portuguese authorities of what you claim, nor of the fact that they have admitted that with hindsight they were wrong to do what they did.
I am not as you attempt to claim, making excuses. I am simply explaining the fact that it is only in hindsight that the practice can be seen to be wrong and even then did not equate to neglect.
