The problem is that mixing business and law enforcement, so that quotidian commercial transactions become opportunities for criminal investigation, can and historically has lead to unintended consequences.

Quoting from a below comment:

> Replacing "undocumented immigrant" with "jew" or "same-sex couple" or "interracial couple" or "movie torrent pirate"... surely one of those substitutions triggers a reaction in even the most law-and-order out there.

> And most of those categories have been illegal in some states in the US's history.

Little Joey Sanchez was born in Iowa to 3rd generation native-born American citizens. Why should Joey be subject to any more scrutiny than his neighbor, Tom Smith, just because his last name is less Anglo?

I’d be livid if I got hassled everywhere I went simply because German last names are out of vogue this year. You can bet Joey feels the same.
