Norway killings: does media coverage inspire copycats?

I’ve been liveblogging the horrifying events in Norway for the last few days. It’s been harrowing and deeply, deeply sad. A man – whether a madman or a coldly sane fanatic is not yet clear – has murdered 76 people, mostly teenagers, for the crime of living in a country that allows immigration. These events have presented something of a moral dilemma for me.
