Fred,
The last arrest in Jamaica? That is where the 2 million visitors came so your answer would be today. There have already been arrests made today in Jamaica.
And I didnt answer your question about setting private vigilante style guards on the Long Bay beach because I didnt think you could possibly be serious. There are already many more than 4 "guards" on the beach with both the police and the government hired "courtesy cops" that patrol the beach already. They are the ones in the white pith style hats. And that is in addition to the private security guards that are required at each of the hotel properties on the island.
I do not know how you do not see them. At the Cafe Goa webcasts we do for Sunday Brunch you will see at least a half dozen walk by and be caught on our live camera. Some even wave and smile at the camera. Join us and and watch it sometime. It may be enlightening.
