In the event of passengers hauling their luggage off with them , the crew manning the slides do have a dilema , you cannot really send them back to put their luggage back or pile up the luggage at the door so I suppose they have to let them go so to speak . There has been the usual suggestions of lockable overheads , all baggage checked into the hold , fines and so on .
What about the following ; Anyone with luggage retrieved during an emergency evacuation will have to give it up and basically forfeit it for 3 months before they are allowed to pass thro back into the terminal . The only thing that they will be allowed to retain is essential medical supplys , everything else is retained and can only be collected / reclaimed at their own expence after the 3 month period has expired . Failure to collect for a duration of one month after this and the goods will be destroyed or handed over for charities. If this is widely publicised and highlighted on the conditions of travel
I am sure the message would soon get through and this stupidity would for the most part cease .
