Or has terrorism against Americans only just begun? New Orleans.

And what is exactly is the difference between Boston and New Orleans incidents? Guns not bombs? From Yahoo news: "FBI spokeswoman Mary Beth Romig told reporters that the shooting was "strictly an act of street violence in New Orleans," not at an act of terrorism. The AP reports that nearly 400 people had shown up for the parade but 200 were in the direct area where the shots went off."
