I agree with your observation but Mediterranean disaster had coverage since last week at least in European news I am following.
This accident will also soon disappear from the news since we now know the fate.
the US and Canadian coast guards don't operate in the Mediterranean, and (presumably) couldn't have gotten ships there fast enough to do anything about it, anyways.
I don't know. Do you ?
From wikipedia: "Immediately following the sinking, the Greek Coast Guard and the military initiated a massive search and rescue operation."
It wouldn't be surprising that some of those rescue ships were funded by the families of the victims, considering the size of their bank accounts.
