In cities, we have a system of regulated meat shops. Only that meat is legalized, which is slaughtered in government run slaughter houses. There is a stamp on each carcass, whether it is a cow, goat, sheep or camel. So, Pork is out of question because it will not be slaughtered in slaughter houses. Other thing is wild bores are found in our Country but not farmed pigs. Wild bores are found mainly in jungles, which are hunted also. You can find videos on Wild bore hunting in Pakistan on youtube also.
If some minority community like to eat pork or dog or whatever, there is no law to prosecute him. Its only illegal to sell it openly or fraudulently sold to general public.
Like yesterday, there was a thread running about butchers arrested in Karachi for selling dog meat. Yes, thats illegal.
So, if someone is capable enough to hunt a wild bore and then eat it. He is allowed as per Pakistani law. Yes, if he is a muslim, he will come under law if reported.
