"Perhaps [the assailants] have been emboldened by the flabbiness of the state in dealing with them." Indeed, behavior that is rewarded tends to be repeated. "HRCP alarmed by assault on non-Muslims," from [1] The Nation, September 10 (thanks to Twostellas):

LAHORE - The Human Rights Commission of Pakistan (HRCP) has expressed acute concern at serious excesses against non-Muslims in Pannu Aqil, Sindh. A statement issued by the Commission on Friday said: “HRCP is extremely distressed and shocked at the atrocities reported against non-Muslims residents of Pannu Aqil.

HRCP has received reports of houses burnt, property looted and women violated. This is absolutely intolerable. Those who commit excesses against non-Muslims are among the worst enemies of Pakistan, but perhaps they have been emboldened by the flabbiness of the state in dealing with them.

The government must intervene to save the citizens from this savagery and try those who riled up and led the mob to attack the non-Muslims and heaped shame upon the nation by their barbaric actions.”
