I must admit that the Eqyptian terrorists' targeting of toursits makes me less likely to travel there. For me, safety is not just about statistical risk. If my risk of dying in countries A and B is equal, but the risk in A is by accident and in B by murder, I would feel much less safe in B. It's very disturbing to me on a human level that I'm in a subgroup of people (tourists) that others are specifically trying to kill.
