On Saturday, there was an explosion in a lab at the National Institute of Standards and Technology (NIST) in Montgomery County, which injured a security officer. But in a lab where lots of chemicals are handled, that sort of thing must be par for the course, right? Not exactly, it turns out.

According to the Washington Post, the Montgomery County police have announced that the explosion was consistent with the manufacture of methamphetamine… or in other words, we may have a real Walter White situation on our hands. The police, of course, are being cagey, saying only that the situation remains “an open investigation.”

Here’s one more clue: the staff member who was injured also immediately resigned. You draw your own conclusions. I’m going to go ahead and re-watch the first few seasons of Breaking Bad. You know, for research purposes.
