So, David McGowan was a member of the older generation of researchers into the deep state, elite pedophile networks, and how they use entrapment to blackmail politicians and media types.

He died in 2015, not long before Wikileaks released the Podesta emails in March, 2016. If he had still been alive then, I'm sure he would have been all over the Comet Pizza revelations, and everything that has lead to, since.

He invented the term Pedophocracy to stand for the process by which deep state insiders use pedophilic entrapment to acquire control over the government and the media.

He published this huge article summarizing his findings about government/elite pedophile networks that have been happening over decades around the world:

It's also archived here:

It contains lots of references to information that should be useful to Pizzagate researchers. One of the most interesting nuggets of information to me was the fact right at the beginning of the article that a guy, Ralph Underwager, from the False Memory Syndrome Foundation who had been testifying for the defense in many pedophilia cases, wasn't afraid to give an interview with the pedophile publication Paedika. So a guy who appeared on behalf of a victim-shaming organization, who was appearing in court claiming to be an impartial witness on the issue of pedophilia, appeared in a pedophile magazine talking favorably of pedophilia. These guys really thought they were untouchable in those days.
