What stood out to me, so far, is that while the Trump campaign didn't actively conspire with the Russians, they were aware of, and expected to benefit from, the Russians intended course of action.
That is the narrowest exculpation ever, a true "letter of the law" situation. Johnny did not kill his wife or conspire with his lover to kill his wife. However, Johnny knew that his lover was going to kill his wife and expected to benefit from her death and his lover expected that she would also benefit from the death of Johnny's wife. However, Johnny is not guilty of murder or of conspiring to commit murder since Johnny has no duty to proactively interfere, report, stop, etc. his lover from committing that crime.
