Whats Up With White Men And Child Pornography?

So here is the deal, it seems like everyone arrested relating to a child porn case seems to be older White men. Recently Pastor Jerry L. Cannon  was arrested on federal charges of soliciting and distributing child pornography. And it got me thinking, what is it with White men? Why are they fascinated with child porn? Is regular adult porn not good enough?
I'm not trying to be racist, its just a fact, go google it and find out for yourself. It just seems like every mug shot seems to be a White man.
