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."
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.
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.
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.
