let's say a quick hello to john calling from ferndale, washington. what do you say?caller: good morning mr. volsky and bill. i want to thank you guys because, you know, it would be so easy, so easy for us to start speculating. i'm a democrat. it would be so easy to say maybe it was militia. maybe it was north korea. the thing is we don't know and the hardest thing to do is not to know and to reserve your judgment and to keep your powder dry and say we'll find out in good time. until then, we're made of sterner stuff. we're not going to panic. we should be grateful that it wasn't a dirty bomb. it is awful that people have died and people have been maimed and justice will be meeted out but we're not a nation of cowards. >> bill: well said, well said. i read this morning too someone made the point that because this was such a tight security area at the end of the finish line to the marathon, there were no cars in the area. this they been able to pack a car or truck with explosives, it could have been a lot lot worse. >> also, the boston marathon is an elite race. you ha
