What makes a terrorist? Can anyone really say?
There are generalities about poverty, but well-to-do men have gone on killing sprees.
There are accusations about being raised in certain countries, but terrorists pledge fealty to groups halfway around the world.
Religious fervor is cited as a motivator, but not every terrorist is motivated by faith.
And while the "angry loner" is a common movie profile, we regularly see terrorists who have wives and young children. It doesn't seem to stop them.
There is one motivator, however, that is increasingly common in today's breed of terrorist: influence through the internet.
Stories are now emerging about Sayfullo Saipov, the Uzbek immigrant who last week, using a rented truck, mowed down innocent pedestrians in New York City, killing eight and wounding many more.
I took interest in this CNN piece detail: "Authorities say they found a trove of videos and pictures related to ISIS on Saipov's phone: 90 videos full of propaganda, beheadings, instructions on explosives and about 3,800 images, including the ISIS flag and images of the ISIS leader."
Here, folks, is your new terrorist incubator.
In the palm of your hand.
