Not a comprehensive interview. He is just like every other politician - can't see ANY good work done by his opposition.
Gota has some severe charges against him other than for the killing of Lasantha. One is the purchasing of MiG aircraft for US$ 7 million in an improper manner. Another is regarding the misappropriation of Rs. 90 million to renovate the D.A. Rajapaksa memorial. These are major obstacles for him to contest, lest win an election.
Many Tamils hate him for having masterminded the defeat of their hero, Prabakaran, and Muslims hate him for forming the BBS.
His authoritarian streak will also be a factor (like how Sarath Fonseka fared). Gota's character is not as amiable as Mahinda's who is a champion of it.
