Well, they did bring boy prostitutes (via Craig Spence?) to the White House in the late 80s, so I guess not everybody in Washington DC is squeaky clean.
I totally agree that "not everybody in Washington DC is squeaky clean". Yes, people with all kinds of nefarious or criminal inclinations can end up in leadership positions and that certainly includes politicians. It's not impossible that some people serving in the US government might have pedophilic inclinations - since 4% of the population is thought to have such problems. But, would seeking out such persons and setting them up with child prostitutes for the purpose of blackmailing them actually give you behind-the-scenes control of the US government, military and industry as conspiracy theorists claim?
The case you referred to, involving Craig Spence, was a homosexual escort service/prostitution "ring". Spence was a client of these companies, he didn't run them. They operated quite openly, for the most part, placing ads for services and using commercial credit card billings. This was not a secret, untraceable, "black-ops" blackmailing operation employeeing brainwashed sex-slaves. It was a gay sex-for-hire service much like you'd find in any major American city at that time. The prostitutes involved seem very typical of the young men & women who get caught up in that lifestyle, often victims of childhood abuse, often drug addicts, but certainly not under mind control or being held against their will in a warehouse or something. Spence did have an involvement with a 15 year old, and it's a tragic fact that teens are sometimes recruited by escort agencies, but there's no credible evidence that these companies specialized in under-age prostitutes or sought clients with such inclinations.
From one of the Washington Times stories:
"The Washington Times story is a rank attempt to sensationalize a fact that should come as no surprise to anybody: that there are gay people in the Republican Party and in this Republican administration," the National Gay & Lesbian Task Force said in a statement. "The story The Times does not tell is the story of the repression and fear that still mars the lives of gay individuals in politics."
The group also challenged the possibility raised in The Times' story of threats to national security from the blackmail of homosexuals in sensitive government positions, saying there has never been "even one single documented case of gay-related espionage" in the past 40 years".
Is there any evidence that this prostitution ring, which was patronized by some lower-level government officials, successfully "compromised" those people and had effective control over the American government? No. The owner/operators were prosecuted and convicted, they were not powerful enough to escape justice.
Spence apparently ran parties from his own home, and connected all kinds of professional people with prostitutes through those parties, but there is only evidence of him successfully blackmailing one person. Another quote from the Washington Times stories reinforces what I stated before, that offering sexual liasons with prostitutes that the targeted guest doesn't have an existing attraction for isn't going to seduce many people, and since pedophilic attraction is thankfully quite rare using children as sexual lures wouldn't net many important or powerful 'fish':
"One man described having a limousine sent to his home by Mr. Spence and being brought to a gathering at which several young men tried to become friendly with him. "I didn't bite; it's not my inclination," the man said. "But he used his homosexual network for all it was worth."
In the end, Craig Spence's schemes to compile wealth and power, including sexual blackmail, don't seem to have given him the power to control governments or even the media. He lost his wealth, got himself arrested, and was reduced to public begging and sleeping in parks before his ignoble passing in a hotel room. In the end, Spence had a big mouth but no power over government, the justice system, or captains of industry.
