I fear M Hills, in her letter ‘Refugee policy irresponsible' (June 30) does not go nearly far enough.

Just today (July 1) a former doctor in New York City went postal and killed someone at his former hospital and wounded six others. Not to forget various other mass shootings ... or US evangelicals regularly bombing abortion clinics in the States which the FBI treats as domestic terrorism. We should ban US tourists because we don't in New Zealand habitually carry concealed handguns or bomb abortion clinics, and they, missing such an essential part of their culture, might feel alienated and start up the culture of mass shootings ... natural born killers, right.

And I've heard it from none other than Michael Moorcock, the Londoner par excellence, that in British cities it is knifings ... let's ban knife-wielding British immigrant and tourist maniacs. Ditto.

I could go on. 'Use every man after his desert, and who should ‘scape whipping?”
