I believe there are three different reasons for most disturbances in Karachi, rather most disturbances all over Pakistan. Two are related to this world and third is related to world here-after (backed by misguided Khawarjee beliefs). All have their own implications, consequences and solutions.
1 … Crime related: People killing and causing disturbances to get wealthy, and to get power (control and influences) in the area, to spread their crime related activities without fear of people (law they buy with money).
Solution: This can get sorted out if corruption, nepotism and mismanagement in government stop, merit becomes norm in job entry, placements, promotions, and hard work is appreciated and rewarded.
End of corruption and nepotism would bring good police officers, honest and fearless judiciary, and honest law enforcement agencies, who can tackle such problem effectively.
Country encouraging merit, eradication of corruption, eradication of nepotism, giving good management and rewarding hard work would make country rich and would create plenty of opportunities for people. That in turn would stop people to take up crime for their living.
2 … Political related: Political parties (or political individuals) killing and causing mayhem for political gain. They may use this technique to intimidate their opponents and give feeling of strength and protection to those who vote and support them.
Solution: This can also end with end of corruption, nepotism, mismanagement, strong and honest law enforcement agencies, judiciary, and police … and obviously with spread of education and liberty (that can only happen when police and judiciary are honest and free).
3 … Religious related: This is the biggest cause of fitna in Pakistan that is spreading in Karachi too.
This is happening in Pakistan because a large group of retarded terrorists under the influence of ‘Khawarjee gurus’ and their Khawarjee beliefs think that killing those who oppose their religious beliefs and creating havoc in Pakistan is their ‘religious Jihad’ that is not only obligatory on them but is the only way that would lead them to Paradise. They are so retarded that for theirs’ this belief, they are even willing to do suicide.
Solution: The way to get rid of this fitna is very difficult, but can be done by fighting this force head-on. It means, fighting and killing these retarded killers wherever they are found, controlling all religious education, venues (Mosques and Madrasas), talks and gathering in country … and punishing severely those who in any way are promoting such people with Khawarjee indoctrination, money, moral support, and by not condemning them.
