These are the questions we need to ask

The ability of two men, a father and son, to carry out a mass-casualty antisemitic attack on a Jewish Hanukkah celebration – the worst terrorist atrocity on Australian soil – raises important questions for our security and intelligence services and the politicians who oversee them.
