That's exactly how I felt too - until I was robbed.
Usually there isn't a problem until there is one. When things go south, it happens very quickly, so don't be complacent just because nothing has happened to you. Tourists ARE being accosted, threatened and robbed in Negril, there is no denying it.
You can make whatever arguments you want to try and soften the facts - ie: per capita comparisons, 'it happens everywhere', etc. But the fact is - it IS happening and it will continue to happen until strong action is take to rout the criminals. But I never see police on the beach at night.
I've noticed a definite change in the famous Negril 'vibe'. It changes for the worse when the sun goes down.
There is a new generation of aggressive 'ganja sellers' and 'rum beggars' on the beach at night now. I don't like their in-your-face approach, nor the look in their eyes.
I rarely venture out at night when I'm alone anymore. I don't want to run the gauntlet. Call it self-preservation intuition.
