I disagree with the argument that this wouldn’t be an act of terror without the media. If it were Milton Keynes, perhaps, but it was done deliberately at the heart of our government. The press could’ve stayed silent as the grave; panic would still ensue.
You’ve also got to look at the role of social media. Twitter was flooded not just by journalists but regular users tweeting their own accounts and rumours. This alone can lead to widespread panic and attention; should we ask Twitter to shut down during an attack?
I agree some of the reporting is irresponsible, but I disagree that not reporting it would lead to taking the power from ISIS. I think it would lead to escalation.
Ultimately, the benefits of responsible reporting (making the public aware, reporting the facts, asking for informants) outweigh the cons (remembering the attack), and it’s not the attackers names that get remembered, it’s the victims. Nobody remembers the names of Lee Rigby’s killers, but most will remember Lee Rigby.
