Other mistake: In the hospital, Barrett had his right arm in a sling and his lower left leg in a cast. When the police/ detectives were trying to find Barrett, one detective said Barrett could not have driven himself somewhere because he had "a cast on his leg." The cast was on the left leg, so Barrett could have driven using his right leg, as usual. Maybe he couldn't have driven with a cast on his right arm, but the detective gave the wrong location of the leg cast. (00:50:30 - 01:13:45)
