Major Plot Hole - Moving the Gun
Alright, so we know the Jackal's purpose for getting and taking the boat across Lake Michigan was to move the gun from Canada to the U.S. Let's consider the sequence of events and where I spotted a MAJOR plot hole:
(1) Jackal acquires a boat at Marina-A in Canada.
(2) He then disassembles his weapon (the high-caliber mounted gun) and stores it on his boat late one evening so as not to attract attention.
(3) The following day, the Jackal transports the weapon from Marina-A in Canada to Marina-B in Chicago via Lake Michigan.
(4) The FBI (w/ Declen and Major Koslova) head to Marina-B in Chicago to intercept the Jackal.
(5) Declen searches the Marina, makes eye contact with the Jackal, and the two engage in a brief shootout.
(6) The Jackal flees the scene in his red minivan.
Okay, folks. Declen knew which boat the Jackal arrived in because he saw the Jackal getting off of it. After the shootout, the FBI surely would have searched that boat up and down and found his weapon. Are we, the audience, to assume that the Jackal off-loaded his high-caliber weapon in broad daylight at a crowded boating event, before the FBI/Declen/Major Koslova arrived at the Marina? This would have required several trips back and forth from the boat to the minivan (as he was hauling a large and disassembled weapon). Note: There is no gun, at least mounted, visible in the minivan when he peels out from the Marina in Chicago. The windows on the car are transparent enough to see this.
I know it's Hollywood etc, but that is TOO BIG of a plot hole for comfort. Like I said, there is no way the Jackal returned to that Marina later in the evening to retrieve his weapon. There is no doubt the FBI would have searched that boat. Either way you cut it, there is a goof to be identified here, or Chicago is full of some oblivious folks to not spot the Jackal casually loading a Rambo gun into the back of a family car. I thought maybe I missed a scene that explained this the first time I watched it; however, I rewatched it today and sure enough events happened as I described them above. Thoughts, opinions, comments etc appreciated.
