Was it in the first 20 minutes of the show? I just turned it on! (I'm on the west coast)
No, it was in the last scene section ( :48-:58) of the show.
I saw that part too and was trying to figure out what was up. Thanks to DVR I backed it up to look.
2 thoughts I had --
Since the bad guy conked the husband out as he was coming around the other side of the vehicle, he stopped dad/Grandpa from safely harnessing the child in when would have gotten in the back seat to sit next to her. Mom/Grandmom didn't expect her husband in the front passenger seat at all-- she never looked to the side and was very startled to see someone else in the back.
-- It was dark and hard to see the harness which was loosely on, except he chest clip wasn't fastened at all. Then again, it would have been more difficult for the cop to reach in there and grab the kid out of harm's way from her insane birth father who hijacked the vehicle in the first place!
LOL -- which was worse -- driving around with a loose harness on the baby or having a loaded shotgun off-safety waving around in a vehicle.
Neither option was anywhere near ideal of a safe ride
I don't think too many parents are going to emulate that wild trip any time soon.
