3. Safety and Security
I had a conversation with a great friend who had been reading about the difference between safety and security. A secure society has agencies to which members of that society can turn for assistance and support, be it police, disaster relief, medical assistance, etc. No one and no society can guarantee safety. Traveling on a train, a loose bolt in a rail and a derailment can easily occur. This can happen at any time and no amount of safety checks will prevent accidents like this. Similarly, terror groups who do not care about their own survival (NOT suicide but homicide attackers, please) voluntarily make themselves accidental phenomena against whom almost no amount of prevention will make a community or a society safe.
