There is still way more to this escape than Tillie getting a hacksaw blade to Matt 5 days before they busted out.
How were the cuts made in their cell walls which allowed them to get onto the catwalk where the power tools were allegedly were kept? This was more than a 5 day job IMO, especially since they could only go into the bowels of the prison to work for a few hours each night.
And who left those power tools unlocked and how did Matt and Sweat even know those tools were back there to begin with? That is, if Matt and Sweat were actually the ones who cut through the steam pipe...which I'm not entirely convinced it was them. It has been said it looks like a professional did it.
And how did they know the exact location of the steam pipe, where to saw from, what was on the other side of the brick wall they had to bust through, and the exact location to cut their exit from the steam pipe? Who gave them blueprints of the prison? Because it sure wasn't a lucky guess on their part.
There are more involved than Tillie and Palmer. MOO
