Government must crack down on this attempt to "shut down" our capital. We know how "peaceful" these protests end up to be.
Businesses are coerced to close, emergency services get paralyzed, local infrastructure is severely and purposely damaged, domestic trade is cut off, government decisions are delayed, influences anarchy in other regions, decays law and order even further, scares away investment, financially harm the stock market, vandalization of public and private property, and since it's our nation's capital; instability will increase not only in Islamabad but through whole of Pakistan as well.
Being an ex-PTI member, I once hung out with these "Youth Wing" members (Sialkot Division); all they did was drive around motorcycles and tear down PMLN signs, intimidate/harass PMLN supporters, vandalize public/private property (by spray painting PTI and PTI slogans), and engage in other criminal activities.
Being an American as well, I know that if any political party in the US (not only the US but any country) threatens to "shutdown" the Capital - then that political party would immediately be banned, leaders arrested, and an overall nation-wide crackdown.
Government must not be lenient.
