Here is a video expert analyzing the video:

They altered the video to make it seem like Acosta lowering his hand was more aggressive towards the woman than it actually was.

I have known some people with zero integrity, but can a person have a negative integrity rating? Appears it indeed may be possible...

Trump, on the campaign trail, said over and over about weakening the First amendment to allow more, easier defamation laws, etc. If he had followed through and succeeded, he and his administration would have hundreds of law suits. What the b!+(% said and did was despicable, however, I don't know about slander in the American court with Acosta being well known.

Good Question Paula.
