As Megan and Larry are walking down the hallway, she shifts some of the papers she is holding so that they are perpendicular to the rest of the papers. When she is shown from the front they are all lined up, but when she is shown from behind again, they are offset.
Around 20m, we see that Larry's FBI pass says, "Escort required" and yet he had no escort when he approached Special Agent Reeves.
Preparing to negotiate with a gunman threatening to detonate explosives in a dump (Bob McHugh/Connor Trinneer), Megan Reeves puts on a ballistic vest which includes a groin protector. Moments later, as she approaches the gunman, she's wearing a different style of vest which lacks the groin panel.
The rifle scopes used by Agent Edgerton and Yardly would be useless if used in real life.
Both scopes lack any sort of central reticule for aiming, and neither scope has any sort of rangefinding capability- which is absolutely essential for precision shooting.
