You and I destroying evidence when accused of a crime? Tampering, a felony in most states.
Send emails to your team and clients that even explicitly says "We need to eliminate documents and emails about this as the US Attorney has already begun investigating us?"
Oh well, no big deal, just have the company pay a fine.
I think it's a reference to the recent killing of that health insurance CEO, where some folks have taken to referring to the killer as an "adjuster."
It's a play on words from the profession of insurance/claims adjuster, which is someone who who arrives to determine what happened and what damage the insurance company is liable for. Unlike the normal version, there's a very different twist on what kinds of damage, responsibility, and consequences are involved...
