If you want to kill a lot of people at scale, you don’t take them out and shoot them or cut their throat and then drag them off. You just feed them into a rotary macerator that outfeeds into a retention pond filled with carp or a trough for a pen of pigs that ends at a retention pond filled with carp.

If you wish to really get those number up, you have train tracks going over the macerator and drop the bottom out of 60° walled railcars.

Look at the area around the prison and see what is that same color, the dirt.
