This is something I found on line. I think is worth reading. Clara (davesgirl).

July 1, 2004 has come and gone, and even people who've never even considered taking a cruise know that, as of that date, major national and international initiatives went into effect to heighten the security of ships and ports. But a reasonably good follow-up to the mega-security improvements would be this: What effect will this have on the safety of cruise passengers ashore? The answer, alas, is probably none directly, though there may be a slight increase in safety within the ports themselves, because of the better fencing, increased surveillance and more intense review of identification documents. But once around the bend from the secured port area, crime stats probably haven't changed. Depending on whom you ask, people's responses to the status quo run the gamut between "There's no difference between the risk abroad and that of any city in the USA," and "As an American I wouldn't travel outside our borders these days under any circumstances." Of course, the truth generally lies somewhere in between, and even though we've all heard of attacks on American tourists in Jamaica, Egypt and even the U.S. Virgin Islands, travel abroad is still a safe endeavor for the vigilant traveler. Still, North Americans need to be extra diligent in their vigilance. Think of preparedness as a three-step program with the acronym "ARM:" Assess the risks; Research the risks; Minimize the risks.
