Sorry I could not find any report made by FBI about LTTE on thier website or major western news media to validate the authenticity of report. Only all Indian media had this news. I hope it is handwork of some vetsted-interst people.
Also who cares whether FBI label badly or praise LTTE. LTTE will carry out thier freedom struggle.
One more thing, how can LTTE be blamed for copying thier tactics by others. They have brain to develop new techniques with limitted resources. Thats thier wealth. If somebody copy ther model, it is thier weakness.
