[T.B. Yoits]

I detest “graffiti artists” and the “art” they bring into our lives, so we have to see it every damn day whether we want to or not.

Yet, those same "artists" are the only ones telling the truth to the public by painting warning signs all over the place to stay away. It's a sign that there are no adults in charge. The government will instead lie to you and even alter or bury crime data.

Graffiti (and litter) are tests to view what government is willing and able to do keep an area clean.

It's an extreme case of "don't shoot the messenger" (regardless of the messenger's motivation).

I must say-I never thought of it in that light!
