Corrected entry: While the film revolves around Ryan, and without him there's no story, he takes part in the operation to stop the terrorist attack, even though, as an operative of the CIA, its charter prohibits him from operating within the United States.
Corrected entry: When Cathy is held in the back of the jeep, her arms are restrained with silver duct tape. When Jack opens the door to rescue her the tape is gone, only to be seen around her wrists.
Correction: It appears to be some sort of strap, rather than sticky tape - it's shown to fly off (in a very brief shot) when the car she's in crashes.
Corrected entry: When Jack Ryan plugs in his laptop and connects to the system of the hyper modern Russian company in a 40+ story building, his laptop shows an 192.168.1.46 IP-address. A company of this size and technology would never use this IP-range. It would only allow 254 devices to connect to the corporate network. (01:05:25)
Correction: It depends on the netmask, if the mask is 255.255.0.0, this network can be as big as 64k. For a large corporation, there are routers and switches connecting the intranet. A private network starting with 192.168 can't tell you how big the company is.
Correction: Incorrect, the CIA can and does operate in the US. The CIA is permitted to act within the US to address the specific areas of foreign intelligence, counter-intelligence, and terrorism (which is exactly what they were working on). They don't operate in the US in regards to domestic threats, which is FBI jurisdiction, although they can give aid if needed. See E.O. 13470. (Specifically section 1.7).
