Same corrupt system has never allowed any single Prime Minister to complete their tenure...Same corrupt system utilized politicians against each other to ensure political instability in order to have their grip firm upto this poor nation's throat. Nawaz Sharif was utizlied against BeNazir in 90s....Imran Khan was utilized agaisnt the rest since 2011. NAB was established to persecute politicians and it has done splendidly well till to date.
'Innocent unless proven guilty'. That's the core esseance of moderN legal structure. No legal system in the entire world can allow any accused to have detained behind bars and ask victim to provide evidence.....
But this is Pakistan and to my Knowledge Imran Khan used this a weapon through the hands of Justice (R) Javed Iqbal whom orgasmic conversation with a lady was nationally televised on each channel...and he opened 92% cases against opposition from 2018 onwards....This is our history.
After recent changes in NAB laws, accused can only be detained for 14 days. Before that almost entire opposition leaders were sent behinds for 3 months on weak fabricated political cases which prosecution failed miserably to defend in courts. So you should be thankful for recent NAB ammendments. Cheers.
