Proportional representation is better at making sure criminals get locked up

We can think about government in more than one way. We can see it as a master of everyone ...an entity which issues orders and threats. Or we can see it more like a jury in a court of law. In the case of a jury we get to choose whether the accused is guilty (and should be excluded from society) or innocent. In the same way when we vote we choose whom to exclude and whom to forgive.

The problem with first past the post is that it does not give us very much precision in this process. Other systems of voting make it easier to be specific about what we want and what we do not want. We can be more specific about whom we want to be represented by. This offers us the opportunity to include (or exclude) people who would otherwise be excluded (included) by the main parties.

Proportional representation is better at making sure criminals (as viewed by the electorate) are punished. First past the post enables criminals to go unprosecuted.
