Because it did not blow up. It was a fire in a mechanical room. Not sure where you are from, but there are fires in mechanical rooms EVERY day is most cities.
You have your head convinced that “they” are out to get us that you cannot see every day occurrences as every day occurrences.
Would you be thinking the same thing I a fire occurred in a mechanical room at the aquarium?
LOL. So whom do you think "they" are who created the Boston Marathon finish line incident?
And moreover, why do you think "they" went after the Marathon that day?
And also, why do you think "they" killed the cop or security cop on the campus after the Marathon?
Just trying to get your "theys" straight.
Because I don't consider the events in your town of the week or so after April 15 2013 as "every day occurrences".
I await your response.
