My father used to suggest that all serious criminals (including murderers) should be given 30 day sentences. And their release from prison should be well-publicized.
If someone from the community wants to be at the appointed time and place and *ahem* “volunteer” for a 30-day sentence, then a lot of neighborhood trash could be disposed of for very little cost.
I vote for.....
Electric bleachers.
Your Father was BRILLIANT!
