Boston bombing attack

Boston bombing suspects had planned July 4 attack

Summary:
The two brothers Tamerlan y Dzhokhar Tsarnaev, were accused for a low enforcement official. 
He said both brothers advanced their attack because they complete the building bombs earlier they thought.
They dettoned the two bombs April 15, the day that boston celebrates a marathon.
Police think they're not the only, they're investigating other suspects because they can destroy peace in Boston and kill a lot of innocent people.

Personal opinion:
At the fisrt time I know that news, I thought it was a joke, but when I read it for a second time I can't believe it. How can a person attack other innocent people? I don't know how, but I think this person is a monster. The world is everyday worst, some people are mad and I think we must do what we can to change it.
