Re: Why not free Qadri ?
The law is clear the courts has their discretion to impose various sentences, including Death or life improvident both are possible for murder case.
Another thing since blasphemy is something very serious matter for every Muslim (although i doubt Salman Taseer committed blasphemy).
One must remember for Muslim respect of Rasool Allah SAW is more important then anything in the world, thus anyone commit a blasphemy should understand that he is causing extreme provocation to any Muslim by doing so.
I do not agree with current law, but there is possible someone kill the person who commit the blasphemy on ground of extreme provocation. Thus entilted for lower end of sentence.
