This isn't a "news story from a credible source," this is a blog post about a Twitter thread and it offers absolutely no context or insight.
What is the protest about? Why is the U.S. Secret Service involved?
The LAPD put out a statement saying they're aware of people exercising their first amendment rights by protesting, and that they'll be on site to ensure public safety. That seems pretty damn reasonable to me. I don't trust the police either, but if you're going to immediately draw a connection between this event and horrific police brutality, please give me something more substantial than "they worded a tweet awkwardly."
"Oniony headlines" lose their impact when they're placed at the top of inflammatory fluff pieces.
