That woman died because she had no power. Life is arbitrary and one can only go to lengths to shut out the gaping void that surrounds them through power – power to ensure freedom. Freedom to survive.
No matter where you live (be that a country like Iran in turmoil with martial law, or a 'developed' and 'enlightened' western country) the same laws apply. The laws are polar and definite: you are alive or you are dead, you have power to survive or you do not. When the end comes (in what ever form) it is the same people regardless of geography that die and the same people that survive.
For example, when Jean Charles de Menezes had six rounds unloaded into the back of his head at point blank range, destroying the top half of his skull, another person died for no reason other than his lack of personal power. A lack of power and freedom that lead him to his death. In 2008 the inquest into his death recorded an open verdict. No reason. No consequences. Menezes had no power (be that financial / social / cultural) and is dead. Police officers and Jury (both with varying levels of power compared to Menezes) are alive.
This woman woke up on that day and found herself living in a man-made system with a fundamental lack of power and she died because of it. She had done nothing but to exist in a reality where – despite narrative / religious human constructs in of which people attempt to live their lives blissfully ignorant to the darkness that surrounds them – everything is arbitrary and you are ever only one arbitrary event away from death.
