Ah the long terms ramifications of this are scary, obama and his loyal band of ignorant followers will use this to go after people who oppose him, watch.Anyways, hope it was a muslim group or north koreans or perhaps left wing terrorists? They were everywhere in the 60's and 70's? Oh yea, they grew up and got jobs in the government and academia
Really though , it is sad and whoever did it should be brought to justice.No excuse for bombing a public event like that, at all.
