Continuity mistake: When Clay fights Anisette at the gas station, her heels change from stilettos to flats. Best visible when Clay throws her on a car, right after she says he should be retired. (00:47:25)
Factual error: The movie is set in the US, but there are several things which aren't found in the US that give away the fact that it was shot in the UK. In one scene, a Tesco superstore can be seen in the background and the lift bridge seen in the film is Kings Ferry Bridge which connects the Isle of Sheppey to the Kent mainland.
Answer: That is a very good point, and something I didn't think of when watching it recently. You are right, the Secret Service would have immediately dragged her to a safe location or even to Marine 1 (the helicopter) to get her safe in the air. As we've even seen in recent history when President Trump was shot in the ear, instantly the Secret Service were on him and dragging him off to safety. This would be a logical mistake breaking what the Service usually would do, but then the climax of the movie couldn't happen if they did it. So it is also likely a deliberate mistake. Good catch.
