Nope. They just forgot.
They also forgot they need to prosecute the “real killer”.
You know, pre-reboot, sometimes, guilty people got way with it. It was the way the show ran. Like real life. This modern reboot no longer feels like real life.
Head slap- Doh!
I can think of a couple errors in the show’s heyday, too.
No doubt. But the writing seemed better.
A couple of times in the old series they had two suspects and couldn’t decide which one was guilty; in those cases, the episode closed without a resolution other than “We did our best”
I remember one of those, involving the bombing of an army recruiting station.
