Corrected entry: Agent Breckinridge claims that Agent Merriweather's firearm still had its safety on despite the fact that he had managed to clear it from its holster. Agent Marin then explains that in the local police academy, officers are trained to "draw your weapon and flip the safety in two separate actions" whereas the Secret Service academy "trains us to draw and flip in a single motion." The problem with these statements is that Secret Service Agents are issued the Sig Sauer P229 pistol as their standard sidearm. This gun has no external safety levers to "flip." (00:17:30)
Corrected entry: When Michael Douglas lets the phone ring in the restaurant in order to distract a Secret Service agent, he quickly slips by. But if the corridor is such a crucial point, an additional Secret Service agent should have been placed there. Even ordinary security companies have any 'vulnerable' position guarded.
Correction: Even though you are correct when you say that even ordinary security companies would have any vulnerable position guarded, this is simply a character mistake by the agent covering that position. The position was supposed to be guarded by the agent Michael Douglas manages to trick. A highly trained security professional should never have been distracted by such an ordinary sound as a phone ringing. Character mistake, not a movie mistake.
Corrected entry: When Michael Douglas' character is kneeling by the garbage can in the alley, if you look closely you will see that there are a series of numbers, but before them is an abbreviation for the state of California (CA) instead of D.C., where they are supposed to be at this particular time.
Correction: CA written on the side of a garbage bin does not necessarily mean it is an abbreviation for the state of California. CA could simply be the beginning of serial numbers for the bins. The company in this town that does sanitation is based from over 600 kilometers away, and serial numbers on the bins don't seem to have anything to do with state or city designations.
Corrected entry: Kiefer Sutherland states that the Canadian US border is 3500 miles long, and that Michael Douglas could slip over the border almost undetected. In fact, the border is 3987 miles long including the water boundaries, or 3145 miles if just including land crossings. These miles do not include the 1538 miles between the state of Alaska and the province of British Columbia and Yukon Territory. If he's estimating the length of the border, he would be more correct to say either 4000 miles or 3000 miles. Someone working with the Secret Service would be more specific due to security training.
Correction: Character choice, not a mistake. Time was a factor, and he did not have time to rattle off all the wonderful geographical facts that accompany your submission. A distance of 4000 miles is more than what is true, and 3000 is not enough, as it is factually more than that. He likely picked the average of the two, which is 3500, which gives a good average, as well as saves time.
Correction: While this is generally true, agents working in a Close Protection detail can also be issued with an FN Five-Seven which has an ambidextrous manual safety.
