When the protests outside the 4th Precinct police station were to be put down, the plan was for the police department to move out the protesters, the fire department to put out their fires, and the sanitation workers to clean up the mess.

Ditty was reportedly concerned about the safety of the workers. They hadn’t been trained in riot zones.

When Ditty saw the video of white supremacists threatening protesters,he knew the situation wasn’t safe. His supervisor had told him he didn’t have a choice; he and the others had to go into the area to clean up the site when the raid on protesters came.

So he sent a news tip to KARE 11, City Pages reports. And KARE 11 turned his email over to the police, it says.
