I have given your question its own thread Alfred.
I could be wrong in this and stand to be corrected by our members resident in Portugal but I cannot see the Portuguese at large being in the least interested in Mr Amaral and his troubles. The Portuguese police had quite a reputation in years gone by and most people have long memories. Interest is probably limited to the Algarve region but guaging support for Amaral in Portugal is probably an impossible task. I could be completely wrong though, please discuss.
Curiously, he certainly enjoys support in the UK but I have a feeling it is more to do with being anti McCann than support for Amaral himself. I think if you took the McCann name out of the equation Amaral would effectively be a non entity. I could be completely wrong though so open this up to other views.
I think at this point we should differentiate between supporting Amaral per se and simply believing his constant smearing both in the UK press and on supporter forums is unfair and unwarranted.
I, like John, believe that most Portuguese people neither think nor care about Amaral and his troubles ( would we be up in arms if a member of SY was facing what Amaral has, probably not ). I think, on the whole the police are seen as a necessary evil in what ever country we look at and Portugal, I suspect, is no different.
