Pakistan's minorities minister was murdered, a few weeks after the murder of the Punjab Governor.  These are senseless and tragic events.  Who are the perpetrators?  In the first case, it might have been the case of misplaced and violent religious fervour.  In the latter, a curious leaflet has been found at the place of the murder - which does NOT appear to be genuine. 

It may well be that the first murder was of misplaced religious sentiment run amok, while the latter may have been an attempt to further aggravate the situation by some interested third parties.  Assassins do not carry leaflets with them.  Well, generally not.
