Do they have laws about printing and accidental exposure?
Neither is illegal in a non-verboten zone.
But as panicky, shrill and vindictive as the anti-gun Coed Special Snowflake Sorority has become, it's not completely un-imaginable that one (or more) of them might imagine that innocuous
printing = brandishing and call the cops in order to "teach somebody a lesson," perhaps based upon another fabrication similar to "hands up don't shoot."
Ironically, this would be the very same police force they protested at City Hall for very professionally keeping Portland's bridges and freeways open during the last tantrum march. Demonstration-prone Portland liberals in skinny jeans don't need to know a DAMN THING about me.
Paranoid? Perhaps. I can handle that label. Packing or not, I go out of my way to remain invisible to all such douche-wagons.
BTW, I'm moving out of Multnomah County before summer. Sure, the weather here will be fine, but this divisive crybaby climate will continue to suck.
