I know this has been said by others and no matter how many times it is restated paste-eaters like Jeff Goldstein will faily to comprehend but I'll give it one more try.
Imagine if 30 people were killed every day by car bombs in US cities. Monday, 30 dead in Denver. Tuesday, 30 dead in San Francisco. Wednesday, 30 dead in Philadelphia. You get the idea.
Now scale that roughly relative to population size. Make that 300 dead per day. Every day. Would the lead story on the evening news be about all the people who weren't blown up that day? No. The country would be completely hysterical.
