some reports put it at 100,000, which shows how varied a number this technique produces. my number comes from 15,000 *reported* civilian deaths, with a 5,000 margin for error to get 20,000. your number assumes that 30,000 people died and no one bothered to report it. you can judge for yourself which method is irresponsible, but i hope you atleast look into where numbers you quote come from in the future.
