Summary
Homeland Security Secretary Kristi Noem has ordered lie detector tests for DHS staff to identify leaks that allegedly foiled immigration raids, including a failed Colorado operation targeting Venezuelan gang members.
The directive, leaked to Bloomberg, requires polygraph questions about unauthorized communications with media and nonprofits. Despite polygraphs’ unreliability, DHS insists they are necessary for national security.
The crackdown follows frustration from Trump’s border czar Tom Homan over compromised raids and aligns with broader MAGA-era efforts to control government communication.
I see your line of thinking, but let’s also remember that polygraphs wouldn’t end leaks even if they really were lie detectors. The most they could do in that fictional scenario would be to reveal the leaks; to sniff them out. To snuff them out would require some additional, separate action.
Also snuff out applies to candles only because the snuff is literally part of a candle’s wick. The phrase is not being used literally here, which leaves us with the common non-literal meaning: to murder.
I still think the most charitable interpretation is that author confused it with sniff out, and failed to consider the grisly meaning of what they wrote.
