If there have been threats made about specific hotels, some people may choose to ignore the threats, whereas others may choose to stay at home.

If there is no danger, why increase security? If there is a slight danger, why wouldn't you inform the public?

My guess is that the authorities are worried the hotels will be emptied if they make a statement. Well, I don't care about keeping the hotels' restaurants full - I want enough information so that I can make a balanced decision about the safety of my family.

And, of course, the newspapers are again complicit in the conspiracy of silence.
