That's kind of where I'm at on this. It's very likely there will indeed be protests tonight, but the "paid protesters" from Portland smacks of the Soros tropes.
While I get that last weekend's protesters probably didn't have a permit to march down Congress, job number one of the cops should be to keep the peace and protect protesters, bystanders, and property. I don't think they did that last weekend even though they had an evident presence given the extremely rapid response time to the shooting.
These quotes from the KXAN story should actually be encouraging:
APD: “We are bringing in the necessary staff, and have partnered with other local law enforcement agencies as we have done throughout the past few months, to allow for those peacefully and lawfully practicing their first amendment rights while also working to prevent any violence or destruction of property.”
DPS: “DPS supports the right of individuals to lawfully protest, and public safety is our top priority. Therefore, DPS will be increasing our presence this weekend, along with our local law enforcement partners, to ensure public safety needs are met and to combat any potential criminal activity.”
Those are absolutely the messages I want to hear.
