Man Of Faith?

Another evangelist has been arrested, this time for child pornography. Do any of these followers ever suspect anything with their "leaders"? I'm not saying all evangel preachers are bad people, but we seem to find quite few. What concerns me is that for all of those who preach modesty and tolerance as a Christian virtue actually listen to these guys in their expensive suits and houses and as they bash other faiths and minorities (i.e. homosexuals).
I have a theory about about this particular case however. In all seriousness, why are children so common among victims in the clergy? My theory is that the religious leaders in any faith that stoops to that repulsive level has been sees an innocence in the children that they preach about, but that they themselves can never attain. The children are, in their minds, physical manifestations of purity, of which they preach. It sounds more like a psychosis, don't you think?
