I do believe, in a time that newspapers are begging for help to keep going, that journalism needs to step up and do the job the public expects and rightly expects, which is to hold institutions and importantly people to account. It is the only way that journalism should survive.
From that perspective, investigative documentaries such as this are important, especially when we consider how important our history is and how easy in such a fast and dynamic world that it is to forget. It has been regularly highlighted recently how our past has continued to influence our present and how it is time for change, to put right wrongs and stop wrongs being the norm.
For this series specifically, I was glad to finally get an understanding of something that happened so long ago, that could have been 'righted', but due to seriously poor failings by metropolitan police, that continue to this day, is still not a closed case. The actual events and aftermath will truly enlighten you as to why, but alas I suspect you won't be surprised by what events have happened and continue to happen to the poor family affected, such is the nature we have become accustomed to these days.
I don't know but do suspect that nothing will change as a result of this documentary, but it's irrelevant, you should watch and understand what goes on inside the institutions we pay to protect us and that often, they shed more blood than they are paid to save.
