On October 14 2020 CBP's Mark Morgan tweeted a very slick promotional video. It had a section showing BORTAC assaulting citizens in Portland:

The men & women of @CBP displayed steadfast devotion to duty & unwavering commitment to this great Nation in FY20. During a pandemic, they remained on the front lines of our borders, working through some of the most adverse conditions. I'm very proud of their accomplishments! 🇺🇸 pic.twitter.com/pkJgE4CHLh

I put in a FOIA for the photos (see response from October 26 2020). Here they are. They're in the public domain. Yay federal dollars paying for fancy photos!
