i want you to realize that that dog that hasn’t barked is trump… VICTIM spent hours at my house with him

The “dog that never barked” can be read several ways, but frankly the one that makes sense given all the context is that Trump knows what was going on, and never balked at what happens around Epstein:

Holmes: “To the curious incident of the dog in the night-time.”

Gregory: “The dog did nothing in the night-time.”

Holmes: “That was the curious incident.”
