When Michael is making the fake ID driver license, at least two errors are shown:
The number starts with "L", yet the last name is Winger. On a Florida drivers license, the number starts with the first letter of the last name, so the number should have started with "W".
The issue date is shown as 1985 with an expiration date of 2012. Florida licenses are only good up to 6 years, so this date is incorrect. Additionally, the 8th and 9th positions of the license number should be the year of birth - which also do not match.
When referring to the "bug" or phone that Michael gives Shannon at the marina, Sam uses the term "10 by 10" in regards to the audio quality. This term is inaccurate for a retired 'Navy Seal'. Sam should have instead said "5 by 5"; meaning that the signal and clarity of the transmission were loud and clear since the scale rating was from 1-5 -- 1 being the worst; 5 being the best.
Fiona tells Michael about a "ka-LISH-ni-kov" rifle. Oops, her character, a supposed arms expert would know that Kalashnikov is pronounced "ka-LASH-ni-kov."
Michael goes to the FAA to get owner data on an aircraft. Unlike motor vehicles, this information is available online. Likewise, the corporation data Michael is paying Barry $1,000 to go to Tallahassee (the state capital) to get is available online.
