UTA recovered from the protets/riots/unrest pretty quickly. The police didn't clear the area until late Saturday night, but, Red Line trains were already running Sunday Morning, and at noon the Library Station - which had been heavily vandalized (paint, smashing glass, etc) - was reopened.

During the protests, all TRAX service north of Central Point (21st south) was suspended, and a lot of bus service was also affected. This was amazingly disrupting for many people who had to work on Saturday - for instance, all the healthcare workers at the hospitals. The Red Line goes to the medical center after all, and I heard that a lot of care workers had trouble getting to their shifts. And all this while daily new coronavirus cases are rising again.
If 2020 has taught us one thing, it should be how interconnected everything is. Shutting down even certain parts of the economy is hugely damaging. Viruses can be spread very far very fast as people interact. Protesting in one place can be deadly for people downstream on the transit line you are blocking.
It's a good reminder for all of us who draw transit lines on maps for a living or for fun - or for anyone really. There are a massive amount of variables and considerations at play, and even potentially small shifts can mean stepping on other people's toes in very harmful/unfair ways.
