The Boston Bombings Discussion

First, please allow me to say that it sickens me to my core that I have to discuss this topic. The thought that anyone thinks that this was not as a result of the Tsarnaev Brothers planting pressure cookers disgusts me as much as anyone who believes that it wasn't Al Quaeda who flew planes into those buildings. However, as it has been so eloquently pointed out to me, I need to keep an open mind and take a serious look at the evidence, ask the questions, and then make a decision. So, I'll do it with as much of an open mind as I possibly can.
This subject was started from another topic that began to discuss the Bombings so I believe it deserves its own place. One of the posts ended with Misha asking several questions. It is from the below comment that I'll begin to look at the evidence:
ProfWag,
If you had read Dave's Boston Bombing thread you will see he used the exact CNN clip which you provided. Yes, Dave addresses the damage to buildings. We have been told by the authorities this was a pressure cooker loaded with nails and ball bearings, correct? Now show me the pitted buildings, snow fence and advertising tarp of such damage. As the CNN clip rightly points out that these two bombs at Boston were NON-DIRECTIONAL devices. That means the shrapnel goes everywhere. Again, show me the damage to structures other than the victims (Glass doesn't count). In fact, why was the glass blown OUT from the building when the device was exploded by or near the street? Take a look at the pictures, please. Why didn't others in the vicinity not hit by projectiles moving 2000 feet per second? Furthermore, since when do bombs only take of Legs? What about arms or hands? Since when do bombs not blow people's genitalia off? Why do all the victims have their LEG pants shredded and not their pants (groin area) shredded and missing? Why didn't the attending physicians not have squirting blood all over them? These are just questions.....
