They posted the full unedited video. It doesn't reveal anything deceptive about the editing of the first edited-for-time video.
EDIT: Going to the substance - you really think Google employees don't want to prevent Trump's re-election? Because every possible indicator (campaign donations, personal speech, company policy) says that they do. The Veritas video is part of a massive pattern of evidence pointing to the same conclusion.
They've got a dog in the fight, and there is no mechanism to stop them abusing their non-accountable, opaque, non-democratic power over the modern mediums of communication.
Another question - If this isn't enough evidence to convince you, what would be? What's the standard or proof? Would you apply that same standard to accusations that, say, Trump wants America to be just white people? Or are you just using an isolated demand for rigor [0]?
