As we've all seen this happen many times, the media can blow things out of proportion, but they can also discover hidden issues or disturbing trends in events. If you don't know what I mean, google Satanic Panic and Watergate, which are two extremes cases (one on each side).
A logical mind would ask:
What is the average tourist death rate in Dominican Republic?
Has it recently changed?
What is the average tourist death rate in other similar Caribbean places?
How does that compare to my city or state, or places I frequently visit?
I have only read a few articles about the recent deaths in Dominican Republic, but I'll bet that no reporter bothered to investigate such questions, since it might soften the sensational and hyperbolic nature of their headlines. Sorry to be such a cynic.
