Same crime but different treatment

Over the last couple of decades, Mutahida Qaumi Movement has learnt to disown it's works, rather the terrorists who fail to remain at large, for example

Crime:

MQM's Rizwan Qureshi burnt 258 people alive for refusing to pay Rs 20 Million extortion.

Similarly, MQM's Saulat Mirza murdered Hakeem Saeed for refusing to pay Rs 20 Million extortion.

Punishment:

MQM wants Rizwan Qureshi to be executed in public.

However, MQM wants Saulat Mirza's execution to be postponed.

Same crime but different treatment.
