The bombings in Boston?

When I first saw the news reports, I wondered what is our government up to now? Anytime I see a spectacular event like Boston, it reminds me of so many other "staged" events like the Kennedy killings, 9-11, Pearl Harbor and on and on which were secretly staged by our own government for their own selfish purpose - usually concerning money or power. I guess not all major events in the world are staged by ours or some other government but it's a good bet they are not that a mere individual out in the streets will ever know or even understand why and how our own government can pull off these devastating deeds right under our noses. It's a very long and old story of how ours and other governments, under the direction of very rich and powerful individuals has been doing horrifying things for 1000s of years while the uninformed public suffers the consequences. I wonder what the bombing in Boston are leading up to for the American ppl and their kids who will be fighting the next carefully selected enemy of this country?
