Dirty cop hands over a file to his prod mates is a scummy thing to do.
Even the government realised, rather a long time ago now, that an even half-credible report into events would need to go well beyond that sort of narrative.
As it is right now we have reached a point where they can be honest about a range of things, but can expresss them as failings and shortcomings, and where vaguely plausible deniability barriers still exist as we get towards the highest levels of state.
This is not surrpising but attempts to get past this and find complete complete certainty in terms of who ordered what, and whether a specific killing was ordered by the elected members of a government itself, as opposed to other elements of state power, capability and decision making literally calling the shots, are always likely to remain murky. A range of possibilities exist, including the elected parts of government setting a policy which encouraged other parts of the state such as the army to employ specific murderous tactics, aided by a suitable degree of turning a blind eye by government. But there is also the possibility of unelected parts of the state at a range of higher levels deciding that they knew best and would manipulate ministers to further their own strategies and tactics, with a private 'democratic' justification that they knew best and were doing what the government wanted really even if a particular minister or cabinet didnt actually know its what was in their best interests.
So, a fair amount of questions about dog wagging tail or tail wagging dog will always remain. However we can get round that when considering overall responsibility by returning the buck to the governments door-step via something like 'they set the mood, the structure of state bodies and ultimately have the power to put the states house in order. Actions by elements of the state which threaten and undermine the overall objectives of the state would be frowned upon and despite allowing for the messy realities, games and power struggles that can exist on so many levels, you might think that those at the top would be rather keen to ensure their most crucial tools of the state were on message'.
Apologies for my possibly unclear and confusing use of language in this post, Im sure there is a better way of putting it.
