It is Draconian... as in Draco Malfoy!
It sounds Draconian, but hopefully it will be only a short-term measure?
Let me speculate on some of the implications of these sudden new rules:
1) With all the additional bags and items presumably going into hold baggage and no additional equipment or personnel (never mind experienced personnel) for examining it, security will be worse, not better.
2) Neither the government nor the airlines would seem to have been assigned any responsibility for loss or damage to items which people are suddenlyl forced to check.
3) Nor does there seem to be any requirement that airlines refund ticket purchases to individuals who cancel their travel, whether for fear own their own personal safety or because there's no point to the trip if they can't be guaranteed that certain of their possessions will arrive intact.
4) As for those who carried their valuable items with them on the outward flight and who now suddenly discover that they won't be allowed to do so on the return leg....
5) Meanwhile, through this government edict, the would-be terrorists have already succeeded in causing a major dislocation to the air travel industry and damage to the psychological well-being of those who travel by air. (Tell an addicted traveler he can't fly, and he'll be angry. Tell him he can fly but then snatch away his security blanket as he boards the plane, and he may panic.)
With the prevalence of laptop computers in business use, and the risk of damage if they are sent as checked baggage, could this effectively shut down the business travel industry? And what about the super-discount airlines, for whom a large portion of their clientele deliberately travels with only carryons?
6) Meanwhile, the news announcement has made sure that any would-be bombers won't be caught in the act, since they've been warned that there's no point in trying today.
Also allowed is "For those traveling with an infant: baby food, milk and sanitary items essential for the flight." So if you want to bomb a plane, carry with you an innocent infant and a bottle of high-explosive "baby formula"?
