You make a good point.
Ethics and Integrity is about what people do when not being watched. One thing I know, there is a reason someone with a record can't get a security clearance and usually it's because they have no integrity. People like this usually don't just stop criminal activity. There are exceptions and some people do learn their lesson.
With this much of a blatant disregard for laws, there is more. This case is not about someone that did not know, misread the regulations, misread a map, or made a mistake and wondered into the wrong area. This person was a guide, therefore he knew what he was doing was wrong and illegal. And was arrogant enough to post on social media. Just my opinion....
