Why there are no reports or links for mass graves in Iraq in 2002?

"I've noticed this question being repeated more than once on the comment section here and on a few other sites.
I want to know why such a question is being asked; would a report about mass graves in 2002 make the situation any different?
Is it that some people think it's too much for Iraqis to get a year off from being buried in mass graves?
Is the question suggesting that all the mass graves fond so far in Iraq do not count if 2002 was free of mass graves?
Or maybe people asking this question are trying to say that Saddam suddenly became a better person in 2002?"
