From your link once he found out that she had lied.
When reached for comment, King directed Fox News to his blog post. When asked if he would apologize to the trooper, King provided this statement: "I would actually like to speak to the officer personally to apologize and to communicate that he was actually a model example of a good cop in this situation. He was patient and thorough. I’ve actually already reached out to try to make that happen."
Being falsely accused does happen. This won't be the first or the last time.
Thankfully the guilty parties have been found via a tip to Shaun King.
If he didn't care he could have sat on the tip. IMO
