Other mistake: A mayday call is received. It is shown on the moving map display as originating to starboard of the boat Magnum and Higgins are on. They promise to go help but turn to port. (00:01:50)
Episode #1.3 - S1-E3
Other mistake: After the arrest of "ABC" and a brief scene with the interview to Betty's family, there's a prolonged close-up of a newspaper with the date "24 April 1933." Besides the article on the serial killer, there's a headline that says "German ministers in Rome - Uproar as Strong Arm men pack benches." The body of the article though talks about the Persian parlament, and the prime minister mentioned is "Dr. Mossadeg." Mohammad Mossadegh's public office as PM and his visit in the US mentioned in the article happened in the 50s.
Warriors and Guardians - S2-E4
Other mistake: The driver in the blue Mustang (Osito) drives past Nolan and Harper, then makes a u-turn and drives past them again, to Nolan and Harper's left (same direction he came from), but when Nolan and Harper go to chase him, they turn right instead of left. (00:31:15)
Undisclosed - S2-E7
Other mistake: Toward the end of the episode the perpetrator is corned by the FBI. He steps backwards from the curb and is killed instantly by a garage truck moving at a high rate of speed. In the following scene the garbage truck is shown just a few steps beyond the scene just behind a parked car. The truck was going very fast when it killed the perp and could not have stopped so quickly. Further it would not have been going that fast in a curb lane with a parked vehicle right ahead of it.
Other mistake: When the first Naranjo brother was shot, blood gets on the glass behind him, implying the bullet exited his head. But if it did, the bullet would have smashed the glass - it didn't.
