Dictatorships by their nature have no concern for human lives. Consequently, the notion that we can agree some set of international standards to promote transparency is doomed to disappointment. Even democracies keep deep dark secrets - the USA being the prime exemplar of this. Human folly will always exceed the very slender stock of human wisdom, and so tragedies are always - and will always be - a fundamental aspect of human existence until the moment we exterminate ourselves entirely due to our unabated capacity for delusional thinking and grotesque stupidity.
