There are various situations where treasonous politicians have been caught engaging in acts that are just too much to leave unpunished.
For instance, a Labour MP calling for the slitting of throats, or another who punched a man for heckling him. I assume.
I consider these people deserving of humiliation. Different grades of punishment would need to be debated and assigned but, in the instance of the first MP, i would suggest a month in the stockade, only allowing one article of clothing depending on the weather, and with a focus on humiliation, not physical harm. So any practices required to prevent strains and such.
Farmers or markets would be allowed to provide rotten tomatoes for a spot of fun.
To be regulated to prevent dangerous assault.
