Ya because, people who plant bombs really, really, REALLY want them to be discovered before they are able to be detonated. They never try to disguise the bombs.
Are you really Mayor Menino's spokesman?
But they were not really bombs, silly.
Perhaps I should have been more clear. My contention is that they were designed to provoke a police response, that would get Aqua Teen Hunger Force front page positioning.
In that sense, they succeeded spectacularly.
If you feel the need to denigrate the Boston Police Force in order to explain why they were spectacularly successful, have at it. No skin off my nose. I am just saying they achieved what they were designed to achieve.
