"hug a hoodie"

The BBC report that:

'BBC political editor Nick Robinson said the Conservatives, under Mr Cameron's leadership, had gone from a party promising to "hug a hoodie" to one willing to allow the public to "bash a burglar".'

There's a problem with that line and that is that as the BBC admit here:

'...David Cameron never says 'hug a hoodie'; that famous phrase was in a press release issued by Labour'

So why is Nick Robinson perpetuating a falsehood?
