I wonder why nighttime bed checks aren't done using some sort of handheld thermal infrared device? It would be harder to spoof IR than just fashioning "dummies from sweatshirts".
And somehow none of the guards heard the "power tools"?
There's a lot more to this story than we've heard so far.

Because those devices cost a lot of money, these events are incredibly rare, the 'cost' to a prison of a successful escape is quite low and prisons have to turn a profit.
