Sir, please point me to the quote where I linked the Boston bombing with 9/11. I beg you to.
You're the one who's interrupting it as such. I never thought any of this was tied to 9/11. In fact, I immediately said, once this was first reported, that people are going to tie this to 9/11.
An act of terror is any action that displays violence towards civilians in order to promote a goal or idea. It has nothing to do with the bomber or past events. Assuming their was a motive behind the bombing, then most likely it is an act of terror.
If however, there is no motive and was merely done to hurt people, it will not be considered as such.
