I keep asking...”Why the Boston Marathon??”. Who would get pissed off at a bunch of runners? Did someone not like getting their property trampled upon? Why those two locations? Did a runner at one time PO the bomber? What is so special about Boston? Will there be more?
”Why the Boston Marathon??”.
Maybe because it’s a well-known event attracting loads of people and media attention? Maybe because it celebrates patriotism?
“Why those two locations?”
The finish line is an obvious choice. Near the finish line? All the families are nearby, wanting to see their loved one cross the finish line.
“Will there be more?”
Do you really need to ask?
Because a lot of white, middle class suburbanites attend this event historically?
Why the Boston Marathon indeed?
Add this to spaced's answers...
The venue is relatively difficult to contain with effective security.
Downtown streets, shops and office buildings containing thousands of people who are not associated with the event.
No gates to control entrance (and exit) where effective security can be employed.
Helluva lot easier to carry a bomb or two into the area than to get one into the Fleet Center or Fenway Park, e.g.
For further perspective, the Marathon is to Boston as the OU-Texas game is to Dallas.
World's largest sporting event.
