You done watched too much CSI if you think the police are on top of things like that lol.
I do watch Forensic Files.And based on that I know they couldve easily figuered out where the sun was in the sky on the video. Slowed the film down to .00002 giga seconds.Identified the dog caught in the reflection of the rear view mirror. Identified the dog by local vet records. And blew this case wide open if they wanted to
