Here is the U.S. there is a little song that is sung about remembering misdeeds of elected officials; the chorus of the song says: We'll remember in November when we vote..." I'm not sure who wrote it or I'd give them the credit due!
In Poland we have a better road sign - a poem by Miłosz.

You who wronged a simple man
Bursting into laughter at the crime,
And kept a pack of fools around you
To mix good and evil, to blur the line,
Though everyone bowed down before you,
Saying virtue and wisdom lit your way,
Striking gold medals in your honor,
Glad to have survived another day,
Do not feel safe. The poet remembers.
You can kill one, but another is born.
The words are written down, the deed, the date.
And you’d have done better with a winter dawn,
A rope, and a branch bowed beneath your weight.
