Yes, it worked for Hoover, and it is still working. But Hoover was corrupt with that practice, his name should be stricken from any recognition. PERIOD!!!
And Trump was inclined to protect the corrupt people or use the blackmail. Either way, he tarnishes his credibility, or he protects those in power or prominent businessmen. I say f*** all of them. I don't care if half of Congress ends in prison over this, and they become convicted child molesters.
At the top of the list is Bill and Hillary Clinton, both went to Epstein Island. If both landed in prison, it would be long over due. Those two have been defecating on everyone on the path of life since they graduated from law school, or what I call corruption school.
