Should Canadian aid workers work in dangerous places around the world?

With the recent release of two Canadian aid workers who were working for the Norwegian Refugee Council there has been discussion about whether Canadian charities or aid workers should work in places that are in the midst of conflict.  Humanitarian workers help save many lives every year - it would be unfortunate if they stopped doing this important work because of terrorists, bandits, pirates and criminals.  That being said, charities need to be aware of the risks, provide training to their employees and volunteers, plan for various contingencies, have necessary equipment and personnel in the field and in some cases, unfortunately it may be necessary for a charity to temporarily or permanently cease operations in a certain area.
