That's foolish. If the only point of laws was to cut crime, you could trivially reduce crime to zero by legalizing everything. Clearly that is not the point.

It's a law intended to help reduce violations of another law.

It has succeeded in doing so.

[mikeash]

Perhaps. It's still not the point of laws in general to reduce crime, as I said.
