If the above was so then how do you explain all the anti-vaxxers? Governments and scientists all around the world are telling their people to get vaccinated and yet many are resistant?
People are far less deferential today than they were yesterday so to speak.
People are under the misapprehension that the appeal system is set up to right wrongs and expose scandals. So if they hear of a criminal being rejected, they assume it is because the criminal is just a 'wrong'un' who has tried their luck and has quite rightly failed in their misplaced endeavour. It's lazy thinking and assumption based. So in that respect, there are always going to be huge swathes of people who run with the official line or the excuses given by EP and clichés surrounding those excuses.
Regarding anti vaxxers - they are made out to be ignorant and stupid. There is no debate - simply a concerted attempt to make dissenters appear to be ill advised and ill educated.
I understand your point that they don't take the official line - however, this about being injected with something, so it brings it home to each person and makes it personal. The Bamber case is at a distance.
