The recent prison break in New York has led people to suggest that they had in house help in escaping using power tools. The should consider that there might have been a 'break in' rather than a 'break out'. People from the outside may have brought power tools and first worked on the way in, then cut holes into the cells and brought the two men and the power tools to the outside. This scheme would allow them more time to cut through the various walls and more access to the tools needed.
