Sorry, stimpy, but I just can't buy what you are selling.
First, Kenya has not been a particularly safe country for a long time. If it was, you wouldn't have people living in walled communities with armed guards. Granted this violence has nothing to do with the recent political disturbances.
Second, violent political disturbances often seem minor, or confined to particular areas, until they erupt into dangerous situations. While I agree that foreigners are not the target of this violence, they can always be caught in the crossfire.
Finally, there are many places in the world which have economic problems similar to Kenya. Why should I take the risk of going to Kenya right now when I could go to Madagascar, Uganda, or Tanzania, instead? My dollars/pounds/euros will do as much good there, I will be safer, and there is less risk that any development benefits that come from my (and other tourists' visits) will be lost in a civil war.
