There are laws, let your stay in Pakistan not make you forget that ever. However, more than that, there is a culture and then up bringing (religious and ethical). Pakistanis in the said case seem to lack all and thus punished.
one should be willing to go back and look into how this culture and that up bringing either religious or ethical develop in people.
a statement is an escape route but one has to debate and narrate to at least what is good for people to know and learn something from.
isn't it state's responsibility to provide education but when people are forced into a certain standard or medium of education which one cannot escape what does parents do?
they can only guide their kids in the name of good upbringing at home, they can educate them with their limited knowledge of religion but a kid has to fight his own war once he leave the house because it is enforced upon him. but where is state who is responsible to provide not only quality education but also has to take a massive part in grooming a child by providing environment.
only then one should talk about ethics, we people of Pakistan are not some breed out of this universe who can't follow the masses. we see children behaving when we see them crossing a road, bin the trash, behave in every aspect of life in the developed world, give them same environment and watch.
and don't blame parents when they themselves are the product of same system then what do you expect from a tunnel mind they'll bring their children up against all odds. it is always opportunities that are provided which help develop a modern society.
a suppressed nation will always behave like what happened in Majid-e-Nabvi, they simply vent their anger out against them with all the privileges they don't justify. putting blame is so easy whereas nobody looks into circumstances and then sentencing them?
what do one expect from a society that lack vision and is totally based on political understanding but is veiled with religion which is deceptive to even their own people let alone expatriates. the result of which is they can't dare touch a "gora" and we talk about justice system they have?
we have examples and many, where Caliphs and wise men of this very religion of the holy land did justice to the convicted on circumstantial grounds, this require vision and dignity which is lacking.
now don't question me why we lack this vision when everyone knows either ruling the country or providing justice or defending the borders or even expanding the vision, culprits are sitting at every place.
then people are blamed when they call out same culprits no matter what.
