Comparing 100+ nights of protests and riots with Jan 6th is ridiculous...one was night after night of the same thing and having a plan in place to defend and the other is a single day where the police lost control and they actually shot someone with real bullets.
Whilst also advising Proud Boys and Three Per Centers of their "enforcement plans", texting them to "take cover" and that they'd be given an "all clear" when they come back out.
Or being advised that although their leaders had active arrest warrants, that they would not be arrested at any protests that were "supervised" by Portland Police Department, so they should "feel free" to come to protests.
And if you are ordering a protest to disperse, you don't tell one side to go home. If you have a curfew (leaving aside opinions there), it's not a curfew for one side.
If you're telling people who have warrants for their arrest that you will actively not only NOT arrest them but protect them, that's not working with them, that's working for them. Which is unsurprising in PDX, given how many LEOs are members of those same organizations.
Nothing in what you said was a good justification. You're right though, it's not a huge surprise that police would choose to work with militant right wing organizations.
January 6th police had real bullets and shot and killed a person. You could argue Jan 6th was handled more strictly than BLM.
They did all that for a photo op vs. Capitol police falling back as far as they could without risking the lives of members of Congress. Even in the aftermath once the building was evacuated and they were clearing the grounds they handled that with kid gloves compared to many of the BLM protests.
This is not how Ottawa is being handled, this is not how January 6th was handled, and if BLM protesters decided they were going to shut down an international bridge that provided 1/3 of trade with the US, that wouldn't have made it a hour before an extreme response was taken.
If the trucker protest were treated like the BLM protests, you'd see people blinded and dead, and it would be completely torn apart every night to have to be reassembled the next day. At least compare it to Occupy, although they were in a park instead of blocking roads.
