Hypothetical

This entire post is just hypothetical - in no way am I saying that any of this actually occurred.

So say someone (probably a male - the reason for this choice will come up soon) was flying for a business trip and due to traffic on some random freeway, oh let's pick a random number - say 5, he was running late and really only made the flight at all because his coworker who was going with him eventually pointed out they could take the car pool lane (assuming this randomly selected freeway number 5 has a car pool lane). Then once they reached the airport the person chose to carry his bag on rather than checking due to the time constraint. When he went through security they scanned the bag and said something along the lines of "bag check, shaving cream". Then the guard that came over said "did you know you cannot bring your shaving cream?". Then upon opening the bag and going through the toiletry kit the security guard discovered toothpaste and after-shave and threw out all these items (let's say the guy was lucky enough that his powdery deodorant was ok - apparently in this hypothetical world you can make a bomb out of a gel but not a powder or a gel covered by a powder).

So the big hypothetical question is: say after all this happened to this person would it be illegal for him to then go to his blog and tell the internet this story which seems to indicate that baggage scanners pick up metal shaving cream containers but probably not toothpaste or after-shave in plastic containers? I'm not sure why it would be illegal to tell this story, but thought it might be interesting to ask about the legality. This is in no way an attempt to tell people what baggage scanners can and cannot detect - it is just a hypothetical question based on a hypothetical situation.
