It would probably be more secret. And it depends what the risk is. If it
was a dirty biological bomb in London, and a riot amongst the populace
who were being prevented from leaving for fear of infecting the rest of
the country, it could well be the best of the three options.

The purple powder incident in the Westminster parliament
demonstrated the difference between plans and reality. The bods
should have been kept in the chamber to prevent potential
contamination of others, but they left.

How one would prevent millions of people leaving London is beyond
me.
