Some empirical data please, Dr Polya

I was unable to find much empirical data on how many perished and if there are any official orders from Ottoman government specifically for extermination of Armenians. Few dozen survivor stories and comments made by Christian missionaries of the time do not amount to any type of proof.  
Most in the West know about this issue through media without any real data, and then assume that it is real.  
 
Could it be real? Maybe. As there are no written evidences, only the tales of survivors, how can we come up with 1.5 million deaths? Did anyone counted? The numbers were half a million in 20s, then 750K; in 80s it went up o 1.5 million. Some today suggest that it was 2 million. Can the number of victims increase 90 years after their deaths?  
 
Why don’t West accept Turkish government's offer for a joint historic research based on empirical data? Is Westerners become such emotionally charged and illogical people in shining armor thinking that they are honoring Armenians while Iraqis are dying in masses as we speak?
