“execute people convicted of vote fraud”
I like your style.
I think that is a little extreme. I would start with putting people in the blocks in the town square, like they did back in the 1600s. People can come along and spit on them.
OR
Like the Taliban did in Afghanistan. Cut the hands off of people in a municipal stadium on national TV.
OK, we can try your suggestions for a few years and see if they work, then fall back to mine.
I’ve prescribed chopping off the hands of graffitists for many years.
