Yes, he means the efficiency of investigations. But he was a policeman from a previous generation, before the internet, phones etc. Thinking is probably a lot different now.
Possibly his training was pre-internet but I suspect phones were available then even in Portugal. :)
But I am not simply talking about phones or the internet. The big media then was television and there is no evidence whatsoever in the early stages that the PJ made any attempt to manage any kind of campaign via television. They were very badly prepared for it and I honestly think forces in other countries would have dealt with the situation better.
Do you really think the way in which the PJ would handle the case has now changed? What evidence do you have for thinking that or do you just hope it has changed?
The crucial point though is whether the collation and interpretation of information by the police which could save the life of a missing child is a waste of time and effort as Amaral states?
I will now repeat the question as you still have avoided it.
Do you think Amaral is right or do you think that such campaigns are valuable and should be encouraged?
