Remember how Muslims were initially blamed for the Oklahoma City bombing? Bloggers and pundits can jump to conclusions, but government officials shouldn’t. Note that Governor Patrick, Mayor Menino, and the Chief of Police also aren’t calling it a terror attack. Let the investigators determine who’s responsible.
Is it your contention that only Moslems can do terror? Oklahoma city was a terror attack.
And this almost certainly was also. If you really must, you can call it an “apparent terror attack”.
