She, actually
. Lower Lobe, that's why I specifically used the eighties. It's also endlessly arguable whether the Hilton bombing was a terrorist attack. The offenders were never caught and no-one claimed responsibility for it, which is unusual with acts of terrorism as the whole idea is to publicise your cause and make people scared. There was actually a successful letter bomber in the eighties (Colin Dunstan), but he was an ex-ATO employee with a grudge rather than a member of a terrorist organization.
Much as bomb jokers annoy me I don't know that charging them actally achieves much. As Biscuit Chucker says, there's no shortage of idiots, and several prosecutions don't seem to have stemmed the tide. I like Mach E Avelli's solution, which Ansett used to do even pre 9/11.
