There are important outreach efforts in our sub-continent. Tabligh movement has global outreach but they are not qualified for interfaith dialogue. Dr Zakir is qualified and a bit confrontational but does not have an organized missionary movement. Mufti Taqi has written some reasonable material about Christianity but laymen in Tabligh movement are out of touch with it . Dr Qadri has tried to visit churches but he is criticized for condoning Christian errors, If we integrate these visions in qualification, compassion and outreach we can minimize these tragic events of blasphemy .
But still we should not ignore the legal element of our religion. In western law, in case of preponderant evidence makes you guilty. For example, the evidence against Dr Afia was not of totally certain nature but still she was sentenced. The idea of complete certainty of evidence is actually Islamic. So, in case of iota of doubt, life imprisonment is more just than execution.
