While I agree with the law enforcement person that the pedophiles are everywhere I don't remember ever hearing any evidence of pedophiles "flocking" to WDW. I would believe there are probably no more and no fewer pedophiles there than there would be anywhere else that people congregate.
It would be kind of hard to prove or disprove simply because ALOT of them never register thier whereabouts, and honestly I lived nextdoor to one for YEARS and never knew.They don't exactly go around with a neon sign .BUT it is truly feasible that they will go where children are found to be..Schools, Malls, Playgrounds and YES themeparks.One of my dearest friends works with trying to rehabilitate pedophiles in prison, and most often they have claimed that they go to where kids are Known to be, and where parents are not , and if the parents are there they are preoccupied.
