"Many on Trinidad believe that the Jamaat al Muslimeen is connected with the recent soaring of violence on Trinidad and Tobago. Last year, 380 people were killed, and 70 were kidnapped for ransom on the islands. The group has been involved with attempting to muscle in on businesses, such as illegal mining activities in quarries in the Valencia and Wallerfield areas, though Jamaat has denied this."
One of America's staunchest opponents in South America was the Guyanan president of the 50s and 60s Chetti Jagan (sis) who was an early supporter of Fidel. A lot of anti American feeling down there, now coupled with Islamic radicalism. I'd bet the Feds are looking at many more people in the Richmond Hill area who work at JFK.
