It is actually up a lot in 2020-2021 including murders and other “real” crimes.
There of course is also an effect where people think all of Portland is on fire because they saw a protest on TV once. But also Portland has had twice as much gun violence this year than all of 2020, which seems like a problem someone should do something about.
Sure, there is a notable bump (with all the usual reporting caveats) in 2020-21; but that doesn't change the general trend. Or at least so far that doesn't seem the case.
That doesn't seem to actually be the case, but crime statistics is a notoriously tricky area.
