the thing about mass murder is that (in the study of it) you quickly get to the point where the numbers, the "count" is among the least important questions; does 5 rather than 6 makes us feel 16% better about what happened? Actually the "6" was a figure Eichmann pulled out of his hat during his trail in Jerusalem; last I looked, some scholars think "5" may be more accurate. Same goes for the 1930-32 Holmador in Ukraine - "count" issues are even murkier (National Socialists kept much better records! - "No one was keeping count" Krushchev - in the thick of the action as a young man - later said.) - Conquest said 5 million just in Ukraine - just from famine ("dekulakization" is a different count!) - but it seems more recent scholarship (Mark Levine) thinks it was rather lower - but he also quickly goes on to the "so what?" point I started with.
