In my opinion I think it’s good thing that this video shows only the basics of how the lock mechanism works as it provides only the basic information about what a person would need to know how to do if they were to attempt to unlock a safe with a lock of this type but doesn’t give away more information than necessary as if someone was to watch this type of video and then attempt to break into a locked safe with this type of dial/combination wheel lock mechanism they would not have as easy a task as this video appears to make it seem as one mistake and it’s all back to the start for another attempt that is of course if they didn’t already get caught and cuffed by the cops by that point in time for attempted theft etc but even if the person knew this videos information they still wouldn’t be guaranteed to be able to successfully open a locked dial combination safe lock as even if a person has the necessary knowledge of how to do the task that doesn’t mean that they are necessarily capable of actually attempting it and successfully completing the task as knowledge only goes so far towards succeeding in a task but it doesn’t guarantee success etc
