This case just escalated.

DOJ has now arrested and charged former SPLC official Heidi Beirich, who ran the organization's project tracking hate groups.

Prosecutors allege Beirich:

• oversaw payments to informants inside white-supremacist groups
• had a romantic relationship with one of those informants
• shared a bank account with him
• and that account contained $140,000 derived from SPLC payments

That personal financial relationship deserves scrutiny.

If there was fraud, self-dealing or deception, prove it and prosecute it.

But follow this case with me, because the government's broader story still raises some remarkable questions.

I recently posted that my employer's matching-gift platform returned my SPLC donation simply because the organization had been indicted.

No conviction.

No trial.

At that point, DOJ hadn't even charged an individual.

Yet the institutional consequences had already begun.

Now look at what DOJ says SPLC was doing:

paying people inside white-supremacist organizations.

Sounds sinister until you ask what those people were actually doing.

One of the informants at the center of the new charges allegedly infiltrated a white-supremacist organization and stole internal documents for SPLC.

And this wasn't some newly discovered practice.

An earlier IRS investigation examined SPLC's informant-payment system. IRS lawyers reportedly concluded that Treasury regulations expressly permitted nonprofit payments to informants providing information about potential criminal activity.

No tax charges resulted.

Investigators also reportedly found that some bank employees knew the supposedly secret accounts were connected to SPLC and helped establish them.

So there are now two very different questions:

Did an SPLC employee improperly mix personal finances with an informant?

That's a legitimate question.

But:

Was SPLC "funding white supremacy" by paying people to infiltrate white-supremacist organizations?

That's a very different claim.

And here is the irony:

DOJ's prosecution could ultimately make it more dangerous for civil-rights organizations to infiltrate the very hate groups they're trying to expose.

Maybe DOJ proves fraud.

Maybe this new arrest produces evidence we haven't seen.

Follow along.

But don't let:

"SPLC paid an infiltrator inside the Klan"

quietly become:

"SPLC funded the Klan."

One could be criminal.

The other could be how you expose the Klan.

That distinction is the whole case.
