At just over 43 minutes into the show the video Special Agent Maggie Bell is supposed to be recording of the terrorist does not match with the person she is recording. The person blinks and the one in the video does not, the lip movements don't match, when he turns his head it is mis-matched, and at the end where he is looking doesn't match the image on the screen.
The "printed" handguns central to the plot could not be fired. As a minimum, the barrels would have to be steel. A common trope of Hollywood's "undetectable gun" fascination.
