I know someone will pipe up and say - crime happens everywhere, but that fact is you need to be viligant. My wife will forever bear a scar on her arm courtesy of a knife wielding purse snatcher. This happened right along the main road running parallel to the beach, around 10 at night, only steps away from the entrance to our hotel. Do not carry large amounts of cash or passports with you. Our biggest material loss was our camera loaded with 2 weeks worth of photos, but the worst thing is our loss of trust among the locals. It never completely turned us off of Jamaica as we are planning our 6th trip there for next winter, but our guard will be set a couple notches higher. Needless to say my wife won't be carrying a purse there anymore.
