Plot hole: In this top level state-of-the-art security prison with transparent walls, cameras everywhere and no civil rights concerns since it's all illegal, there's not a single hidden microphone in the communal parts. Even worse, the wardens never search the inmates, who can smuggle freely all sort of stuff, sometimes in the most blatant way (like when the protagonist gets stitches for his leg).

Plot hole: In the Bendwater escape, the security cameras show the time outside the prison as 15:59, but a few cuts later, there's a shot of Stallone in his cell with the timecode being 15:56. That's not a continuity mistake, since it turns out that Breslin rolled back the security monitor, the problem is, he is shown doing that at 15:57, and barely rolling the tape past the point when he stands up. By the time the guards are looking at the monitor after 16:01, the tape showing him nice and quiet 3 minutes before would have already rolled to the incriminating part where he breaks out of the cell. (00:06:50 - 00:13:25)

Plot hole: The most secure prison in the world, designed with the advanced schematics of world leading prison-building architect (J.D Ray Breslin) has cameras somehow interconnected to one another so tightly that physically neutralizing one puts every other camera out of commission as well.
