What do you mean by saying BJP is responsible for fanning terrorist activities by challenging them? Should every policeman after catching a terrorist planed a kiss each on his left and right cheek and then hug him affectionately for the acts done by him?
TErrorists do not udnerstand the language of peace and should be dealt with mercilessly. When Modi tried to do that all pseudo-secular came out protesting him. There is no harm in shooting dead a terrorist without getting entangled in legal war which take years to complete.
If one your relatives were in that hijacked plane should not have cast aspiration against BJP. But since that is not the case, you can blame BJP for the same.
