Not especially.
It would appear from the phrasing of your OP that you perceive the Mail as being a crusading paper that addresses stories which are not addressed by others.
I suggest that this is according them with a degree of morality and desire to expose uncomfortable truths that would otherwise remain hidden.
The Mail functions like any other daily paper - it adopts and adheres to its agenda which is both supported and driven by its readership - and its primary function is to obtain advertising revenues for its owners.
My point is that, in common with all other papers, the Mail's bottom line is readership and revenue, and the notion that it is crusading is, in my view, erroneous.
