They know the bombs were placed strategically to implement maximum shrapnel damage.
they know that a man of Arabic or Indian(not native american) descent was trying to get into a restricted area about 5-10 minutes before the bombing, and since
No one claimed it, I believe that it is probably a domestic terrorist
The fact it was patriot day, which is a day celebrating the Boston tea party
It may have not been foreign terrorism because it was not their style, I don't mean car bombs either, but it was only 2 bombs in the same place. Terrorists like to hit several locations with much more impact, that is why they chose the subway in Madrid, because there is the bomb itself and the ceiling falling from being destroyed causing much greater damage. The twin towers killed the passangers on the plan, people in the building s as they fell, and people on the street from the falling debris. This racks up the casualties.
Now let's look at it from this angle, the day celebrates the Boston tea party. a day to rebel against tea taxes forced on the US. Obama care as it is called is not that much different, either you get health care or you go to jail. pre-revolutionary war was it not the same penalty for not paying the king's taxes, think about it.
People are comparing this to 9/11, similarities seem to far and in-between. First 3 people died in this, about 2,000 died in 9/11. No one has taken credit for this, within 8 hours Al-Qaeda to credit for 9/11. 9/11 was planned for years lead to a very thorough series of attacks on several US targets. This was a single attack with a single target.
Final question, how many of you knew that an 7.8 earthquake ripped through Pakistan and Iran, killing 68 people also yesterday. The quake was so destructive that it sent the entire country of Iran into a state of emergency.
Once again I am merely an observer I don't think any single perspective is correct or incorrect. So was it domestic or foreign terrorism, and does one tragic incident outweigh the all others ^_^.
