Speaking about abuses, I would expect that in practice the division line between victims suggesting high penalties and those suggesting low penalties would separate the brave from the cowards, rather than the vengeful from the merciful. Thoughts about the criminal waiting in front of my home with words “you swine, you made me spend two more years in jail” aren’t for the faint-hearted.
You could somewhat mitigate that by shifting police forces automatically around prison releases and/or by creating stiff penalties for such vengeance, but I can see your point.
