In reply to Pesda potato:
I think you're on a very slippery slope if we're in a position where our media is ever in a position where it feels it cannot broadcast/publish the full facts of what is going on in the world. Yes, the whole point of terror is to spread fear in a populace, and in the case of Islamic terrorism, to divide people and propagate religious conflict, the media is complicit in this aim, however inadvertently.
But since the terrorists can never kill huge numbers of people (especially compared to the ability of a traditional nation state's armed forces) then all they can do is conduct high profile acts of carnage and hope the fear does the rest*. We need to know what is going on, in order to make decision as informed participants of a democracy. Unfortunately that means the likes Katy Hopkins are free to spout opinions, but I'd still rather live in that kind of society rather than a middle eastern totalitarian theocracy.
Terrorism works to a degree. I work for an international company and we have a huge office in Brussels - every day we have dozens of people travelling in or out of there and we've all been told to suspend travel there until further notice. This has a knock on effect, damages confidence, fewer hotel beds filled, restaurants taking bookings etc. Life does get back to normal though.
