Other mistake: The shopkeeper hands Danny a Beretta 92fs/M9 handgun with a detached suppressor. To mount a suppressor to the muzzle end of the handgun the barrel needs to be threaded, and this one isn't. Sometimes barrels are threaded and when no suppressor is attached they are protected by a thread barrel cap to protect the threads from dings and bumps. There is no thread cap here either. (00:22:35)
Other mistake: The man flying under the alias Darius Kazim is listed on a passenger manifest for a large flight with several dozen if not hundred other passengers on flight number 4540 seated in 3G, but the plane he boards is a twin engine Cessna maybe capable of carrying max 8 people with flight crew included.
