But he did not commit a crime with weapons in your example.
No, that's not true. He then would have committed the felony of having weapons in a secure zone, in addition to his other crimes, in that hypothetical case.
My point was that he committed a serious crime, and that it really shouldn't be seen as "innocent" because such an action as running past security could have caused awful consequences for other people. If hundreds of other people ran past security to "save time," and some weren't caught, would you feel the same about such a security breach?
He inconvenienced thousands of people for his own selfish gain. Hundreds or thousands of people will have missed flight connections and may even have had trouble rescheduling their flights, and may have missed important events. Airlines and businesses lost money. It's not so innocent.
If other people decide to copy his example, airport security will be even more overburdened and air travel will become impossibly difficult. He deserves far more punishment than a $1000 fine.
No he didn't. The Feds aren't charging him with anything, and the state won't charge him with anything serious, i.e., anything that requires criminal intent as an element. You really don't know the full meaning of the words "serious crime".
