British police have arrested 21 men in a foiled plot to smuggle explosives on to as many as ten commercial aircraft to cause the deaths of thousands, according to this BBC report.
And here's the kicker:
According to BBC sources the "principal characters" suspected of being involved in the plot were British-born. There are also understood to be links to Pakistan.
British-born, to be sure, but very likely raised from the cradle to hate Britain and all that it stands for, with the help of both the public education system and the local mosque.
Just like the Toronto 17.
