My ultimate take on the article is "so what?"

Yes, fraud is bad. I agreed before I read the article.

I've learned (from the article) that there was apparently some fraud in Minnesota, some of which was successfully prosecuted and, possibly, some that wasn't.

If pressed, I would say the take away from the article is that the fraud investigators should have been more willing to use race/ethnicity and accept a lower standard of evidence before taking action.

Is there something I'm missing?

That's what I'm getting from this article too. It's giving "Nick Shirley in the style of lots of extra words".
