Episode #1.1 - S1-E1
Factual error: The American flag shown waving outside the White House is the current present-day flag with 50 stars. From 1896 to 1908, (the time period that this show is set in) the US flag only had 45 stars as Oklahoma, New Mexico, Nebraska, Alaska and Hawaii were not recognised as states in that time period. The flag did not have 50 stars until 1960. (00:04:30)
Nothing Seems the Same - S4-E1
Factual error: Nothing Seems the Same: The bus has Seattle Department of Corrections printed on the side. There is no Seattle Department of Corrections. Corrections in Seattle are done by King County Jail or Washington State Department of Corrections. (00:05:07)
Factual error: Sergeant Bumpher never wears any rank insignia. He appears to just be a constable.
