Murder of Avijit Roy and other killings

It has become imperative now for all of us to sit down together and think how to stop killings in the name of religion and politics such as murders of Avijit Roy and others innocent. We urge all Bangladeshi social, religious and political institutions to lend their hands in stopping such killings and forced disappearances to uphold democracy and freedom of speech in Bangladesh.
Murder of Avijit Roy indicates that mass killings of the innocent and opponents will only be leading  the voices of dissent into fundamentalism. Have we not learned anything about radicalism from the past experiences in history of religious and political wars?
Can we not respect other religions by saying "Your religion is only for you and my religion or disbelief is only for me"?
We acknowledge that murders of non-believers, believers of other religions, or political opposition in countries like Bangladesh and across the world, including the killings of political and religious extremists without proper justice is absolutely unlawful and impractical.
 It is true that banning any religious party and student wing will not prevent radicalisation in Bangladesh. We need to re-think about this suggestion that is delivered from all quarters, national and international ones.
The Avijit killing and many other murders across the country including ethnic people in the Chittagong Hill Tracts areas indicate that the government has failed to uphold secularism and multiculturalism in the country.  And recent  killings by petrol bombs clearly indicate that political parties have lost their moral values entirely. It is clear that power greed has led these political parties to become unjust, insane and inhuman.  
The authorities should be careful about a likely naive decision of arresting Dr Kamal Hossain or Editor Mahfuz Anam for 'treachery', as none of them has any political purpose besides expressing people's rights and democracy.  Rather this sort of reckless speeches seeking arrest of Dr Kamal Hossain or Editor Mahfuz Anam will have serious consequences.
