If you destroy a city block (including a school), that's how many you're probably gonna kill. It's not like he went all serial killer to get that number, most were from that single incident.

I go to a school for a city of only 30 thousand and we have an enrollment of 1700 in three grades alone. That's what I'm basing the death toll on.

Ninjaed XD @Kidd, you're right.
