Allow me to digress:
I believe a mistake we make with these Islamic-inspired attacks is to attribute the problem to ISIS rather than the more bellicose scripture calling for this kind of behavior.
ISIS is certainly one important aspect of the problem, but it is only a symptom of a larger problem that is found within the Koran. Simply put, there are, in effect, two Korans: the Mecca Koran and the Medina Koran. The first was written when the prophet of Islam had few followers while in Mecca, perhaps 250 in all. But as the religion grew and Mohammed traveled to Medina, he had over 10,000 followers all willing to fight and die for him.
The Meccan Koran was far more tolerant of other religions than the Medina Koran and it is this later portion of Islamic scripture that jihadis follow.
And they can justify following the latter Koran because of abrogation--the directive to obey that which came later and is better in the scripture. Of course, that questions the idea of why would a supposedly 'perfect book' need to be abrogated in the first place, but that never gets discussed by Mohammed or later scholars.
Back to the incident:
The FBI told Fox News that it's investigating the dual stabbing along with Roanoke County Police Department in order to determine if it is a possible terrorism-related incident.
Special agent in charge of the case, Adam Lee, said that the FBI is working with the local police but added, "While I cannot discuss details of the investigation at this time, I do want to reassure the community that we are working to determine the nature of the incident."
ABC News said that Farooqui traveled to Turkey last year and may have tried to sneak into Syria to fight for ISIS.
Witnesses in the apartment complex where the attack took place said that Farooqui was yelling "Allahu Akbar" as he stabbed the two victims, a man and a woman. Both are in serious condition.
It's a mystery as to why Wasil Farooqui would want to kill perfect strangers, as this appears to be the case. A total mystery.
