But i think it was only much later when i started working with like, massive data sets, and i realize that it's a kind of the direction in which there's most change it. So, if you can't use it to kill someone, i mean, lok, you're not interested. This show has gone very odd, hasn't itits the opposite is how to stop people killing by working out why they kill and where, using mats. I'm realy interested.
