I'm just saying that I think a "half truth" is a thing, and not just media jargon. Don't take my word on it though, it's in the Merriam-Webster Dictionary and the Collins Dictionary.

>From a legalistic standpoint, "the whole truth" refers to the truthful statement plus context or suggested evidence to support the truthful statement. The "whole truth" does not imply there is any ambiguity around the factual occurrence of the event/etc in question based on context.

TheLawDictionary.org defines a half-truth as:

"a deceitful act where only part of the truth is told where all of the truth will lead to a different conclusion."

This reads to me like there is ambiguity due to the lack of full context.
