I agree with many of those points. The problem I have is that article contains enough suspicious information that it's easy for a reader to assume the other points are cherry-picked in order to justify a specific political viewpoint.

In other words, it isn't convincing and I don't think it's a good link for this context. Others might be:

These talk more about the justice involved, without getting into misinterpretable numbers like the Reason article did.

Anyway, for the original questioner, try doing a search for "War on DUI" for more essays like these.
