It's really tiresome defending Jamaica to people that don't or won't understand the "runnings".
Kingston (and Jamaica) are as safe as New York City. There are areas that are wonderful and areas that you shouldn't enter.
Tour ports are known for overzealous panhandlers, "tour guides" and trinket salesmen.
Jamaica is a poor country, and tourists with bling, fancy cameras etc. are all rich.
Fact is that serious crime against tourists is almost nonexistent.
