The Usual Suspects are all over this one:

Of course there is an explanation. Amrani was a Muslim and he was waging his personal Jihad against the infidels. After over 18,000 terrorist attacks by the followers of the religion of peace sincer 9/11, the only thing that is inexplicable and indeed shocking is the surprise of the politicians to connect the dots and that these terrorists are Muslims and they are practicing the many teachings of their prophet.

But they’re dead silent when one of their own picks off Muslims on the streets of Florence.

The corporate media, it must be said, aren’t much better: as of this writing, 5,890 Google News hits for “Amrani” and 1,700 hits for “Casseri.”
