They made a big mistake because I think this operation was designed to kill a lot more people than it did. Too many people seem to have known that something evil was brewing in Boston. People were warned prior to the race.
The mission and objective they set out to accomplish was not achieved because so few people died. More people die on Americans highways every hour compared to what happened in Boston. Ban cars? No.
Everyone and their mother is waiting to hear and see who did it.
Weird how the state run media knew within minutes of the Towers being hit that Bin Laden was responsible...but when someone plants a couple of garbage bombs with cameras all over the place, they do nothing but speculate and imply that the Boston massacre was caused by a domestic, "right wing terrorist."
Never be afraid to ask simple questions.
