Someone mentioned that they think that the reason they chose to shoot the video inside the sister’s home was to get law enforcement inside without a search wIfarrant enabling them to snoop and not raise the family’s suspicion.
That wouldn't happen. They have to go through all the correct processes, ie warrants - dotting i and crossing t
They'd not be able to use anything if it wasn't discovered through the correct process. Immediate family are always first to be looked at so it's normal. LE had already been there before the video to kidnappers was shot.
