That by itself does little but the announcement that in the unlikely event of an evacuation all carry on found outside the airplane will be confiscated as part of the criminal investigation would make people think.
Could add a bit of sugar by stating that returned carry on after evac would have a $100 reward attached to it.
The $100 reward is a great idea, even $50 would do, perhaps. Lots of people here are saying 'you'll never change human behavior" but the advertising industry doesn't see it that way: they change human behavior every day.
