I guess just like the Panama papers, leading journalists will be killed, investigations stop being reported in mainstream media, and the world goes quiet again with nothing changing.
E.g. In Denmark, the country’s tax minister cited the Panama Papers to justify hiring hundreds of new employees to bolster the fight against tax fraud.
It was high news and had consequences. There is much work to be done, but 'nothing changing' is not the case.
There were no earth shattering mass arrests and government topplings, but it's unrealistic to expect such a thing.
I guess you are referring to Daphne Caruana Galizia. That would still be singular, though.
