Apparently the most frequently vandalized sign on TriMet is the one offering a reward for turning in vandals. I’m going to hazard a guess that it’s the sign above, which somehow made it through QA checking with a typo. It reads:
It is a felony under oregon law to assault a TriMet operator or vandalizes TriMet property
And I’ve noticed, sure enough, on a lot of them someone very carefully has crossed out the final “s” in “vandalizes”, as there is a lack of subject-verb agreement there.
I suppose yes, that’s vandalization in and of itself, but in a way I think it’s just someone engaging in copyediting for the sake of making the sign accurate.
