And why?

Unlike the previous bombs, the latest victims were white. They may not have been specifically targeted - the tripwire is set to go off when the first person who comes along trips the bomb. But why? Does he have some motive like the Unabomber did? Or is he just trying to scare the bejeezus out of everyone?

It does take a certain amount of skill in making one of these bombs, to keep from blowing yourself up while making it. But there is no shortage of instructions on the internet and elsewhere on making these things.

The real skill is doing this without being identified on surveillance cameras, which this fellow seems pretty good at doing.

There's a $100,000 reward for this guy. Anyone have any ideas?
