The message from IS to Muslims all over the world is for them to act to kill infidels. People with mental health problems are the ideal candidates for that message... but that doesn't mean it isn't terrorism. It's the instant denial that makes me angry. Why not say nothing rather than imply it's anything else but terrorism when the likelihood is that is was carried out in the name of IS.

And Sadiq Khan... "I urge Londoners to remain calm & vigilant". Unnecessary advice.
