Sohrabuddin had cases registered against him for goondagiri much before his death and this was also reported in India Today magazine (which I presume is not "saffron"). It was also reported that most security agencies were aware of the threats and criminal activities of that guy. Of course, this did not give anyone the right to bump him off, a fact that Modi also publicly endorsed. That Modi later brought up Sohrabuddin as an election issue should not be seen singularly and narrowly, as Modi's opponents do not fare better.
I am not holding a candle for Narayan Murthy (and am surprised his name is being selectively added to justify the survival of secular jokers), but it must be understood that most "secularists" are paper tigers and can only show their mite against the Hindu community, given the point that most Hindus are extremely tolerant and will not retaliate/throw books/chappals/declare a fatwa against those who write & act derogatively against them. If these "secularists" have spine, let us see them flexing their cardboard muscles against the few fundamentalist Muslims (who bring such a bad name for their community). I bet these guys will not have the guts to do so. One does not need too much intelligence to understand their morality and courage (proof of which is their deafening silence on the Anti-Sikh riots of '84, where thousands of that proud community were looted, raped, chopped and set on fire by Congress goons). You still think these guys have stuff?
