For someone portrayed as a trained professional, Frank breaches at least two fundamental firearms safety rules by pointing a loaded weapon at people he doesn't intend to shoot. First, during a discussion about security with Henry, he points his Browning High Power straight at Henry. Then, in the cabin incident, the moment he chambers a round into the High Power he trains it squarely at Nicki's face while telling her to stay still.
As Frank explains to the limousine chauffeur the latter's new role as his assistant, he inexplicably points one of his pistols straight at him. A former Secret Service agent would always be mindful of where the muzzle was aimed and would never, under any circumstances, point a weapon at someone absentmindedly.
In the closing scene where Frank is acting as security at the political function, the clergy are asked to deliver the "benediction" at the start of the meeting. A benediction is customarily given at the end of a service, not at its beginning. The prayer offered at the outset of a service or meeting of this nature is correctly termed the "invocation."
Marron's son Fletcher is said to be unable to swim at the lake; however, he has a swimming pool at his home and owns swimming trunks.
There appears to be some confusion about the lead character's name throughout the film. In the credits she is listed as "Rachel Marron", yet her surname is spelt differently in some of the death-threat notes. Additionally, when the limousine pulls up outside the club midway through the film a fan holds up a brightly coloured sign that reads "We Love Rachael" — with an extra "a".
When Rachel looks at Frank's football photo, he says he played as an end, but at the cabin his father claimed he was the finest wide receiver.
When Frank takes Fletcher out on the motorboat, he doesn't fit him with a lifejacket, despite Rachel having said that "Fletcher isn't a very good swimmer". Given Frank's duty as Fletcher's bodyguard and protector, it seems improbable that he would neglect to do so.
When trying to leave the club in a hurry, Frank rings Henry to have the limousine brought round, using the standard soft‑plastic in‑ear radio earpieces. It is impossible to converse with one another inside the club because the speakers are so loud they prevent any communication, as shown when Henry could not hear Frank say 'change of plan'.
