Weakened dam stable but 'extremely volatile'

My favorite headline from today, a quote from the Mayor of Mill River, Massachusettes, about their dam that is on the brink of collapsing:

"Weakened dam stable but extremely volatile"

Am I mistaken, or is that completely self contradictory? Stable and volatile, huh?

Keep an eye on this mayor--it sounds like he may have a bright future in politics!
