Unfortunately, we live in a world today where terrorist attacks have become far too common. Counter-terrorism strategies and tactics are rightly in the consciousness of governments, employers and the public at large in the wake of attacks in Kenya, Beirut, Paris, Nice and many other locations around the world which experienced massive losses of life by the actions of extremists (not to mention the numerous shootings, bombings, and bio-attacks that continue to take place). In August 2016 there was a terrorist attack on a Pakistan hospital which killed more than 50 people.23 Locally, we have had our own challenges with the loss of life arising from the Martin Place Siege and attack on NSW Police Headquarters in Parramatta.
