Corrected entry: When talking about the planned robbery of Fenway, the florist mentions a four-game series with New York. However, later the crew is in a bar and a clip of the baseball game is being shown on the television. The game being shown is against Toronto. Since this scene is supposed to be just prior to the heist, one would expect the visiting team to be the Yankees, not the Blue Jays.
Corrected entry: Near the end, when Doug drives the MBTA Bus to the train station and then boards the train, he is actually at the Anderson Woburn station north of Boston, where the trains only run to the north of Boston and not south, such as to Florida.
Corrected entry: When Desmond Elden is shot in the head in the garage of the ballpark, the SWAT member pulls the charging handle of the rifle which wastes a round that hasn't been used. Even if he ran out of ammo he would not have to pull the charging handle but simply slap the bolt release on the side of the rifle after changing magazines.
Corrected entry: There is no such company as "Boston Ambulance" (as seen on the ambulance and uniforms in the park scene). The city is serviced by Boston EMS, which also doesn't use any of the converted van-style ambulances.
