The picture is not of a Rasta it's of a gringo which is one reason I asked Harriet to revise her post (not delete). The other was that the wording implies that nothing was or has been done about poisoning. Harriet is just not aware of the efforts that were and are being made.
No dogs should be running free no matter who owns them. They should be in a fenced yard or on a tie out and should be supplied with sufficient shelter, food and water. If all dog owners on the island adhered to that philosophy there would be a lot fewer strays and a lot fewer problems.
