Archaeological confusion

So i was researching about Genghis Khan a little (Some people might believe i have a fixation about despotic tyrants, i for one care less for them. No more than the average chilean expatriate, at least), and came across this four-year-old piece of news:

ULAN BATOR, Mongolia -- An American-Mongolian expedition
believes it may have uncovered the burial ground of
legendary conqueror Genghis Khan.

The New York Times reports the expedition has uncovered
a walled burial ground some 200 miles northeast of the
Mongolian capital, Ulan Bator.

According to legend, all those in attendance at the
funeral of Genghis Khan in 1227 were killed to preserve
the secrecy of the tomb site.

The site has remained a mystery ever since.

My first thoughts upon reading this were: Oh no! now they're going to have to kill those poor archaeologists!
