I suppose it depends on how you want to live. I am sure the people shopping at the Santa Monica, CA farmer's market a few years ago thought they were pretty safe until the elderly man drove his car into the crowd, killing 10 and injuring 50. I don't believe any government warned about that risk, or the risk of a massive tsunami that would kill several hundred thousand people and displace millions.

I felt totally safe in Jerusalem last week at all times of the day and night. There were numerous trained guards around that checked bags when entering restaurants and shops (similar to what I have experienced in Paris). I don’t think my safety was any more at risk than if I had stayed locked in my home and risked fire, tornados or raging snowstorms. I am not stupid, but I only have one life to live, and I want to really live it. I am VERY glad I went to Israel and look forward to returning soon.
