looks staged to me
I’m suspicious too.
I took a job one summer, for a large chain grocery store; as part of the orientation, the store manager took me through the operation, which included a short explanation of their store security camera room. He said, no one was assigned to watch the monitors; a corporate security guy came through once a month, to make sure all the equipment was working okay; VHS tape at the time. He mentioned that they only used the tape if an employee or customer reported a theft; used it as proof to police.
I know this isn’t the Netherlands, but in our state you need to leave the premises with the pilfered item, B4 it is considered shoplifted. So that girl would have had to pass the front portal of the store to be considered a shoplifter.
