The press has no compunction about being hypocrites. It has accomplished the desired affect against Trump with the accusation of violence against Fields, and now will move on to amplify that accusation with the next story, the lawsuit in Kentucky.
All the while, violence at approved candidates' rallies will go without repetition.
Just saying, "consistency" is never part of the press calculus when creating and maintaining the narrative.
The biggest paradigm shift is social media. The press simply no longer has control over the narrative. Trump has over 15 million on his social media. With re-tweets probably over 30 million.
People are already very, very leery of media so they go to the web to find out what is happening.
By now most people know this is totally bogus.
