Read the article and discussion for a law that an Oregon state senator is trying to pass that would imprison anyone convicted of "terrorism" for 25 years to life.
Qualifying crimes evidently include "receipt of stolen mail", "second degree theft", "unlawful labeling of a videotape recording", "prostitution", and even strikes.
Note that my interpretation of this is uninformed and should not be taken as what's really going on, and it's quite possible that Minnis is just being a complete blowhard and using this as an attempt to look tough on the Portland protests that weren't anywhere near as violent as the press seems to have described them to be.
Update: Here's local coverage. Note how the bill's author is also the moderator of the discussion and threatens to clear the room.
