Brett Kavanaugh: Key senators back embattled Supreme Court choice the BBC News can use analogies that Conservative MPs can't

This BBC report https://www.bbc.co.uk/news/world-us-canada-45766729 includes some 'Analysis' from, in my view TDS sufferer, Anthony Zurcher, BBC North America reporter:

'... Now that the bombs have been thrown, it's time to assess the fallout.'

Presumably at the BBC it's a good thing to use 'bombs' analogies but not 'suicide vests', but I don't see the massive difference in offence caused by the two expressions.
