See, this is where you've blown your cover and have shown yourself as a troll. What you're saying is that hijackers can only be passengers and therefore these security measures are good and getting better. There are so many loopholes as yet unclosed that further molesting passengers, and this now can be qualified as molestation, is a diminishing returns.
Someone else here said and I agree, this is really starting to feel like more overt discouragement from air travel. It's almost as if the TSA has decided that the best way to stop hijacking and bombing of passenger planes is to eliminate passenger planes altogether. I sure as hell will not want to travel to the US by air anymore.
