What does flight check-in times has to do with extreme vetting? US visas are already granted after extreme vetting and pre 9/11 ease of moving around is not coming back anytime soon. Concordes are not flying purely for safety and business reasons and not terrorism and sot com bubble and the 2008 market crash happened because of corporate greed which is what affects many more lives than fear and paranoia. Our country already extremely vets, tracks the movement and stay of Pakistani nationals inside our borders. I know of a few people who have married Pakistani nationals and stay in Mumbai. They undergo the most inhumane scrutiny. You want an ankle bracelet on you when you live in the US? Terrorist attacks in India have seldom been committed by visa travellers. It has either been disgruntled natives like Tiger memon colluding with corrupt Indian officials or poor security infrastructure which leads to ttacks over water. I am sorry but you have no idea what you are talking about.
