Unfortunately with the Boston bombings, there will likely never be a satisfactory answer to the question 'why?' However, Time does do a good job in summarizing some of the most pressing questions that do need to be answered about recent attacks. Four Enduring Mysteries About the Boston Bombings
Did They Really Act On Their Own? During his initial interrogation, Dzhokhar Tsarnaev reportedly said that he and his brother Tamerlan acted alone, motivated by anger over America’s wars in Iraq and Afghanistan, and that they learned how to construct their bombs online. Officials have disclosed no evidence to the contrary, but there are hints of a more complex plot. By some accounts, their bomb detonators–exploded via remote controllers for toy cars–required a sophistication that the Tsarnaev brothers didn’t otherwise show when, for instance, they failed to wear disguises to the marathon site, or when they carelessly allowed a hostage to escape. “There was some outside counsel to these individuals on how to build and how to detonate,” House Intelligence Committee Chairman Mike Rogers told Fox News last week, although a national security source also told Fox that the toy-car detonator is not a known al Qaeda technique.
