Personally, I don't think that we should worry about lone suicide bombers unless it becomes an issue. Israel is justified in considering lone suicide bombers in their security planning, the US... not so much. Also, it's a matter of practicality/trade-offs. A lot of airports are isolated, and it takes less money to secure an airport perimeter than it does to secure (using your example) Times Square. There is a middle ground. The attitude doesn't have to be "we can't protect everything from suicide bombers, therefore we should attempt to protect nothing."
